According to a new survey by Gallup, "Republican voters who prefer Newt Gingrich for the party's 2012 presidential nomination are as likely to name Mitt Romney as their second choice as they are to name Rick Santorum, suggesting the race would not tilt in Santorum's favor if Gingrich dropped out." Here is Gallup's chart:

Two Polls suggest a Romney victory in tomorrow's Illinois primary. We Ask America reports that Romney leads the race with 37%, followed by Rick Santorum at 31%, Newt Gingrich at 14% and Ron Paul at 8%.

In the state with the second biggest pool of GOP delegates--Texas--the momentum appears to be shifting away from Mitt Romney.

A new national Fox News Latino poll of likely Latino voters reports that "73% approve of Obama’s performance in office, with over half those questioned looking favorably upon his handling of the healthcare debate and the economy, at 66% and 58% respectively. . . . the poll shows that the overwhelming choice among likely Latino voters is President Obama. In head-to-head match-ups none of the GOP candidates would garner more than 14 percent of the Latino vote come November." If these numbers can be sustained, PollTrack believes that it would be extremely difficult, if not impossible, for a GOP candidate to make up the difference. The poll is very good news for the President's reelection effort and a warning to Republicans.

Here are polling updates from PollTrack on the upcoming GOP primary and causes race for tomorrow's Super Tuesday sweep.

Georgia: Landmark/Rosetta Stone shows a possible Newt Gingrich romp in the state, with the former house speaker way ahead of the GOP presidential field in his home state with 42%, followed by Mitt Romney at 22%, Rick Santorum at 16% and Ron Paul at 5%.

PollTrack's aggregate of polling in today's Michigan GOP presidential primary--four polls released on Monday are included--suggest a very close race, with Mitt Romney the very slight favorite over Rick Santorum. Our poll average in Michigan places Romney at 37.5% over Santorum, with 35.8% Both Ron Paul and Newt Gingrich are far behind, with well under 15% each. Polling in the field last night, however, shows overnight momentum by Santorum. With a scant 1.5% lead in our aggregate, the race appears VERY close with the potential for a Santorum upset.

A just released survey from American Research Group reports that Mitt Romney maintains a slim lead in the Arizona GOP primary at 39%, followed by Rick Santorum at 35%, Newt Gingrich at 11% and Ron Paul at 9%.

Two new polls out this morning show that Mitt Romney has regained the lead over Rick Santorum in the Michigan GOP primary. A poll by Mitchell/Rosetta Stone irepoorts that has Romney with a small lead over Santorum,, 36% to 33%, with Ron Paul at 12% and Newt Gingrich at 9%. Another 11% are still undecided. And Rasmussen shows Romney leading Santorum by six points, 40% to 36%. According to the former survey, "Romney has made big inroads with conservatives over the past ten days: 16% lead among Tea Party voters has been erased and he is now tied with them; his 16% lead with Evangelical Christians has now been cut in half to 8%, and Santorums 31% lead with self-identified conservatives has now been cut to 13%."

In what may be a serious problem for GOP prospects in November, a new survey by Associated Press-GfK reports that interest in the Republican presidential race is on the wane: Just 40% of Republicans say they have a great deal of interest in following the contest, compared with 48% in December. Just as ominous for the GOP, the poll finds that a mere 23% are "strongly satisfied" with the field and 40% said they are dissatisfied with the candidates running.

Although President Obama's standing in many of the swing states--including Pennsylvania, Michigan, and Ohio--have show improvement in recent weeks, his standing in one state, Iowa, is actually in decline. A poll by the Des Moines Register in Iowa shows the president trailing three of the four Republican candidates in head-to-head match-ups: Ron Paul, who leads Obama by +7%, 49% to 42%. Rick Santorum leads 48% to 44%. Mitt Romney leads Obama 46% to 44%. The president defeats only Newt Gingrich, 51% to 37%. PollTrack moves Iowa on Today's Map from Too-Close-Too-Call to Leaning Republican.

Who is leading in the Michigan GOP primary. Recent polling remain somewhat inconclusive. A new survey by American Research Group reports that Rick Santorum leads the state's GOP presidential primary with 37%, followed by Mitt Romney at 32%, Ron Paul at 15% and Newt Gingrich at 10%. Another poll, by Inside Michigan Politics, reports a much closer race, with Mitt Romney and Rick Santorum tied with 33% each, followed by Ron Paul at 7% and Newt Gingrich at 5%. Stay tuned to PollTrack this week for the latest polling in what could be a make or break state for the two leading candidates.

A new survey by Detroit News in Michigan reports that Rick Santorum now leads Mitt Romney by +4%--34% to 30%, followed by Newt Gingrich at 12% and Ron Paul 9%.

As PollTrack noted yesterday, the tide appears to be turning in favor of the president's reelection. Two new polls, hypothetical matchups for the fall election, confirm this observation.  A survey by CNN/Opinion Research reports that President Obama bests all of his possible Republican rivals in GOP match ups: Obama leads Romney, 51% to 46%, tops Santorum, 52% to 45%, beats Paul, 52% to 45%, and crushes Gingrich, 55% to 42%.

Another poll, by Fox News, of key battleground states -- Colorado, Florida, Iowa, Nevada, New Mexico, North Carolina, Pennsylvania, Ohio, Virginia and Wisconsin -- reports the same: Obama leads Romney, 47% to 39%, tops Santorum, 48% to 38%, beats Paul 48% to 37% and crushes Gingrich, 52% to 32%.

A new poll by Quinnipiac in Ohio reports that Rick Santorum now leads Mitt Romney among likely GOP primary voters, 36% to 29%, followed by Newt Gingrich at 20% and Ron Paul at 9%.

A slew of new polls out over the weekend suggest the the race for the GOP nomination for president has a new frontrunner: Rick Santorum. PollTrack also notes that these national polls are also backed up by local state polls also showing Santorum in the lead, such as in Michigan and Pennsylvania, states where Romney had been leading as little as three weeks ago. On the natiional front, a just released survey by New York Times/CBS News reports that Santorum is surging among Republican primary voters nationwide, "lifted by support among conservatives, evangelical Christians and Tea Party supporters." In the poll, Santorum leads with 30%, followed by Mitt Romney at 27%, Ron Paul at 12% and Newt Gingrich at 10%.

A survey by Tribune-Review/WPXI-TV in Pennsylvania reports that  Rick Santorum's support has more than doubled in his home state, though its primary is more than two months away. Santorum now leads with 30% (six weeks ago he was at 14%), followed by Romney at 29% and Newt Gingrich at 13%.

A new poll by Mitchell Research in Michigan reports that Mitt Romney holds a comfortable lead in the GOP primary race with 31%, followed by Newt Gingrich at 16%, Rick Santorum at 15% and Ron Paul at 15%. Since the poll was conducted before Romney lost contests in three states earlier this week, PollTrack will be following this race closely in the next few days.

A survey by Public Policy Polling in Colorado finds Mitt Romney primed for another big win in today's caucuses. The poll reports that Romney is ahead of the pack with 40%, followed by Rick Santorum at 26%, Newt Gingrich at 18% and Ron Paul at 12%.

A just released survey by Public Policy Polling in Minnesota reports a very close race heading into Tuesday's caucuses. Rick Santorum bests Mitt Romney, by a mere +2%, 29% to 27%, with Newt Gingrich at 22% and Ron Paul at 19%.

A just released survey by Public Policy Polling in Nevada reports that Mitt Romney is headed for a big victory in tomorrow's caucuses. Romney leads Newt Gingrich, 50% to 25%, with Ron Paul at 15% and Rick Santorum at 8%. PPP observes that "the bad news for Gingrich isn't just that's headed for a distant second place finish. Nevada Republicans actively dislike him, with only 41% holding a favorable opinion of him to 49% with a negative one. That's an indication that GOP voters might be starting to sour on him again, sending his numbers back to pre-South Carolina levels."Nevertheless, Nevada does not have a direct primary, so polling may not accurately reflect the make up of tomorrow's participants. Still, PollTrack these numbers--consistent with other recent polls in the state--suggest a Romney win.

Mitt Romney's substantial victory in yesterday's Florida primary may give him a significant advantage in the GOP presidential nomination contest, but many more primaries and caucuses lie ahead for the Republican field. Here's a breakdown for February:

• Nevada caucuses - February 4
• Maine caucuses - February 4-11
• Minnesota caucuses - February 7
• Missouri primary - February 7
• Colorado caucuses - February 7
• Arizona primary - February 28
• Michigan primary - February 29

A new USAToday/Gallup survey of the dozen states likely to determine the outcome of November's election--Colorado, Florida, Iowa, Michigan, Nevada, New Hampshire, New Mexico, North Carolina, Ohio, Pennsylvania, Virginia and Wisconsin--concludes that Mitt Romney is the "GOP contender with the best chance of denying Obama a second term." The poll reports that "in a head-to-head race, Romney leads Obama by a statistically insignificant percentage point, 48%-47% . . . But Obama leads Gingrich, 54%-40%. The president's standing against him has risen nine points since early December; Gingrich has fallen by eight. Gingrich fares less well than Texas Rep. Ron Paul, who trails Obama by seven points, 50%-43%, and former Pennsylvania senator Rick Santorum, who also trails by seven points, 51%-44%."

PollTrack's analysis of half-dozen polls released over the past few days in the GOP presidential primary in Florida suggest a likely win for Mitt Romney. Romney's aggregate lead over his closes competitor, Newt Gingrich, as of Sunday evening is +11.3%--a considerable advantage, with Romney leading in all six polls (with margins ranging from +8% to +16%.

A survey by CNN-Time in Florida reports a slight lead for Mitt Romney, who now comes in at 36%, followed by Newt Gingrich at 34%, Rick Santorum at 11% and Ron Paul at 9%. According to the poll, "Romney leads Gingrich among female and white voters, voters over 50, and those with a college degree... Gingrich holds leads among men, Tea Party voters, self-identified conservatives -- among whom he boasts a 10-point advantage -- and born-again Christians. His fans also appear to be more committed than Romney's."

A just released survey by Public Policy Polling survey in Florida reports that Newt Gingrich now leads Mitt Romney by five points in the GOP presidential race, 38% to 33%, followed by Rick Santorum at 13% and Ron Paul at 10%. Significantly, Gingrich has gained 12 points since a PPP poll conducted in Florida a week ago. Romney has dropped 8 points.

A new poll out from Rasmussen in Florida shows Newt Gingrich now ahead in the GOP presidential race with 41%, followed by Mitt Romney at 32%, Rick Santorum at 11% and Ron Paul at 8%.

In another sign that the Romney campaign is ion trouble, a new survey by Insider Advantage reports that Newt Gingrich is ahead in the Florida GOP presidential primary. After weeks of leading significantly in the polls in the state, Romney now trails Gingrichby eight points in Florida, according to the poll conducted the day after the former House speaker won the South Carolina primary According Insider Advantage poll, Gingrich is at 34%, Romney 26%, Ron Paul 13% and former Rick Santorum is last at 11%.

After a month with a clear advantage in South Carolina, four new polls suggest that Mitt Romney may now be the underdog in the state's upcoming GOP presidential primary.

A survey by American Research Group reports that Newt Gingrich now leads, with 33% closely followed by Mitt Romney 32%, Ron Paul 19%, Rick Santorum 9%, Rick Perry 4%.

InsiderAdvantage shows Gingrich leading with 32%, followed by Romney at 29%, Paul at 15%, Santorum at 11%, and Rick Perry far behind at 3%.

We Ask America reports that Gingrich leads the GOP field with 32%, followed by Mitt Romney at 28%, Ron Paul at 13%, Rick Santorum at 9%, Rick Perry at 3% and Jon Huntsman at 3%.

And a survey by Public Policy Polling survey show Gingrich with 35%, Romney with 29%, and Paul and Santorum each tied for third at 15%.

PollTrack notes that Perry's departure from the race could also help Gingrich, removing as it does one less conservative alternative to Romney.

A new survey by Sunshine State News in Florida reports that Mitt Romney leads by a very wide margin in the upcoming primary for the GOP presidential nomination. According to the poll, Romney leads with 46%, followed by Newt Gingrich at 20%, Rick Santorum at 12% and Ron Paul at 9%. Similarly,. A new Public Policy Polling survey in the state shows Romney in the lead at 41%, followed by Newt Gingrich at 26%, Rick Santorum at 11%, Ron Paul at 10%, Rick Perry at 4%, and Buddy Roemer at 1% rounding out the field.

Three new polls show Mitt Romney with a significant lead in next Saturday's South Carolina GOP presidential primary:

InsiderAdvantage: Romney is at 32%, followed by Newt Gingrich at 21%, Ron Paul at 14%, Rick Santorum at 13%, Jon Huntsman at 6% and Rick Perry at 5%.

Reuters/Ipsos Romney leads with 37%, followed by Ron Paul at Rick Santorum at 16% and Newt Gingrich dropping back to 16%.

Frontier Strategy: Romney is at with 32%, followed by Gingrich at 23%, Santorum at 14%, Paul at 10%, Perry at 6% and Huntsman at 4%.

Two new polls show Mitt Romney pull way from the pack in the race for the GOP presidential nomination. A survey from Fox News reports that Romney leads with 40%, followed by Rick Santorum at 15%, Newt Gingrich at 14%, Ron Paul at 13%, Rick Perry at 6% and Jon Huntsman at 5%. Gallup daily tracking similarly reports that Romney is at 37%, Santorum at 14%, Gingrich at 13%, Paul at 12%, Perry at 5% and Hunstman at 3%.

Even if the South Carolina proves to be close--or even if current frontrunner Mitt Romney loses--a new Rasmussen survey in Florida suggests that Florida may contribute to his overall standing as GOP nomination leader. According to the poll, Romney leads with 41%, followed by Newt Gingrich at 19%, Rick Santorum at 15%, Ron Paul at 9% and Jon Hunstman at 5%.

As of Tuesday--and therefore before the results of the New Hampshire primary--Mitt Romney continues to hold a very modest lead in South Carolina, according to two polls: A survey by We Ask America reports that Mitt Romney leads the GOP presidential field with 26%, followed by Newt Gingrich at 21%, Rick Santorum at 13%, Ron Paul at 8%, Rick Perry at 5% and John Hunstman at 4%. Another 22% are still undecided. A new Public Policy Polling survey shows Romney at 27%, Gingrich at 23%, Santorum at 18%, Ron Paul at 8%, Rick Perry at 7% and Jon Huntsman at 4%.

A survey by Quinnipiac in Florida reports that Mitt Romney is now leading the GOP presidential race with 36%, followed by Newt Gingrich at 24%, Rick Santorum at 16%, Ron Paul at 10%, Rick Perry at 5% and Jon Huntsman at 2%. With more than half of all voters saying they could still change their mind, the race may still be fluid.

Polling in recent days has shown surprising strength for Mitt Romney in the relative conservative state of South Carolina. A new Public Policy Polling survey in the state reports that Mitt Romney holds a modest lead, with 30%, followed by Newt Gingrich at 23%, Rick Santorum at 19%, Ron Paul at 9%, Rick Perry at 5%, Jon Huntsman at 4%, and Buddy Roemer at 1%.

With a slew of new polls showing Romney ahead in New Hampshire, PollTrack wonders by how much and who will be his closest challenger. A new poll from Public Policy Polling reports that Mitt Romney has a substantial lead in the Republican presidential race with 35%, followed by Ron Paul at 18%, Jon Huntsman at 16%, Newt Gingrich at 12%, Rick Santorum at 11%, Buddy Roemer at 3% and Rick Perry at 1%. A new survey by WMUR/UNH reports an even great for Romney, with 41%, followed by Paul at 17%, Huntsman at 11%, Santorum at 11%, Gingrich at 8%, Rick Perry at 1% and Buddy Roemer at 1%. But a Suffolk University tracking poll, released over the weekend, shows Mitt Romney's support dipping for the fourth day in a row. By Sunday, for example, Romney dropped another 4 points overnight to 35%, followed by Ron Paul at 20%, Jon Hunstman at 11%, Newt Gingrich at 9%, Rick Santorum at 8% and Rick Perry at 1%. Another 15% remain undecided.

With some polls showing Huntsman gaining momentum (but Santorum loosing steam), the race could end with a closer result than a simple Romney walk. New Hampshire is known for its surprises: Hillary Clinton won the primary in 2008, although Barack Obama came into election day with a lead in virtually every poll. While PollTrack still believes Romney--thus moving him considerably closer to the nomination--will win the New Hampshire Primary, the depth and intensity of his win remains uncertain.

Another poll in New Hampshire, this one by Suffolk University, reports that Mitt Romney holds a huge lead, now at 41%, in the GOP presidential primary, followed by Ron Paul at 18%, Rick Santorum at 8%, Newt Gingrich at 7%, Jon Huntsman at 7% and Rick Perry at 1%.

Has Rick Santorum's strong second place showing in Iowa helped him in the upcoming New Hampshire primary? And new poll by CNN  suggests the answer may be only marginally, reporting that the Iowa caucus results appear to have changed few minds in New Hampshire, at least among likely GOP primary voters who watched the caucus results on Tuesday evening. The poll shows Mitt Romney with a staggering 47% lead, with Ron Paul at 17% and Jon Huntsman at 13%. As for Rick Santorum: the poll reports a modest, but by no means consequential, bump for him among Iowa caucus-watchers: he's now at 10%, from 5% a month earlier.
