With a GOP pick up for Governor in PA, it now appears that the US Senate seat will also go to the Republicans. Republican Toomey defeats Democrat Sestak, 51% to 49%. 

The GOP has picked up three Governor's seats:

New Mexico: Martinez, REP

Pennsylvania: Corbett, REP

Michigan: Synder, REP

The GOP also holds one seat in South Carolina: Halley

As many Democratic held seats change hands in the US House, a surprising number of US Senate races remain competitive for Democrats: races in Pennsylvania, Nevada, Colorado, Illinois remain too close to call. Republican candidates were in the lead in all of these races in pre-election polling for these states. This may could be a long evening.

The final Muhlenberg/Morning Call tracking survey in Pennsylvania suggest that tomorrow's race may come down to a photo finish: incumbent Sen. Arlen Specter and challenger Rep. Joe Sestak are tied in the Democratic U.S. Senate primary race at 44%.

A just released Suffolk University poll in Pennsylvania reports that Democratic Rep. Joe Sestak now lead incumbent Sen. Arlen Specter in the Democratic Senate primary by +9%, 49% to 40%, with another 12% undecided. That a five-point jump from earlier in the week.

A new poll suggest that incumbent Democratic U.S. Senator Arlen Specter is in Danger in his reelection bid in Pennsylvania. In the Democratic primary, the survey shows Specter behind rival Joe Sestak. In Monday's Muhlenberg/Morning Call tracking poll: Rep. Sestak leads Sen. Specter by +5%--47% to 42%. A new Rasmussen survey also shows Sestak with a +5% lead, 47% to 42%.

This week, Polltrack looks at races it rates as a Toss Up for 2010 US Senate.

Here is the poll average for PENNSYLVANIA:

Toomey (R) 44.0% to Specter (D) 41.0%.

Slight edge to the Republican, but the race is a true toss up. The tea leaves are, at this point, very difficult to read. It appears that Specter's number have been improving in recent months.

A new DailyKos/Research 2000 poll in Pennsylvania reports that incumbent U.S. Senator Arlen Specter has a modest lead Republican Pat Toomey, 47% to 41%. Other surveys have also reported movement in Specter's direction in recent weeks.

A new Franklin & Marshall poll in Pennsylvania finds Republican Pat Toomey leading both potential democratic rivals Sen. Arlen Specter and Rep. Joe Sestak by double-digits in general election match ups. Toomey bests Specter, 44% to 34%, and leads Sestak, 38% to 20%. Nevertheless, with a large undecided block, PollTrack continues to rate the race a toss up.

According to PollTrack's first read of Democrat US Senator Arlen Specter's 2010 reelection bid in Pennsylvania, neither party has an edge. PollTrack First Call: Toss Up.

A just released Quinnipiac University survey reports that if the 2010 US Senate Election in PA were held today, incumbent Senator Arlen Specter (D) and former Rep. Pat Toomey would be in a dead heat, tied at 44 percent. In the Democratic primary, Specter is surprisingly strong, boasting a 20 point lead over Rep. Joe Sestak (D-Pa.), 50 percent to 30 percent, according to the poll in the Democratic primary scheduled for April 2010.

Former Republican, now turned Democratic, US Senator Arlen Specter is in deep trouble in his 2010 PA reelection bid, according to a new Franklin and Marshall survey: His job approval rating has dropped from 52% to 34% over the past three months. Even more ominous for Specter is that the proportion of state residents who believe he deserves re-election has declined from 40% to 28%. His numbers are tepid even among members of his recently adopted party: 43% of Democrats say Specter deserves re-election; 39% say no. In a hypothetical primary match up with Rep. Joe Sestak (D-PA), Specter leads 33% to 13%. Nevertheless, and quite significantly, 48% remain undecided.

Is there a ray of hope for the GOP in its efforts to unseat newly minted Democrat US Senator Arlen Specter in his 2010 reelection drive in Pennsylvania? Perhaps: "Former Pennsylvania Gov. Tom Ridge (R) is considering running for the U.S. Senate nomination in his home state." According to Roll Call and reported by Political Wire, national Republicans "have been publicly and privately urging Ridge to consider a Senate bid since Sen. Arlen Specter (D-PA) announced earlier this week that he was switching parties and would run for re-election as a Democrat in 2010." Ridge's 'moderate politics and national profile would make him a more viable candidatei in the general election than former Rep. Pat Toomey (R-PA)." A new Susquehanna Polling & Research poll also finds Ridge would edge Specter, 39% to 38%, in a match up for U.S. Senate.

According to Political Wire, "as a result of Sen. Arlen Specter's decision to run for re-election as a Democrat, CQ Politics is changing its rating of the Pennsylvania U.S. Senate race to "Leans Democratic" from the tossup category, "No Clear Favorite." Similarly, the Cook Political Report changed its rating to Leans Democratic and the Rothenberg Political Report now rates the race as Clear Advantage for the Incumbent Party." What a difference a day can make.

One major reason why incumbent US Senator Arlen Spector jumped to the Democratic party yesterday: he remains very unpopular with fellow Republicans in Pennsylvania. According to a recent poll, the moderate sentaor trailed former conservative Congressman Pat Toomey by 21 points in "an early look at Pennsylvania’s 2010 Republican Primary. 51% of Republican voters statewide say they’d vote for Toomey while just 30% would support Specter. Specter is viewed favorably by 42% of Pennsylvania Republicans and unfavorably by 55%, according to a new Rasmussen Reports telephone survey of voters in the state. Those are stunningly poor numbers for a long-term incumbent senator. Specter was first elected to the Senate in 1980." The Senator chances appear much stronger with Democrats, with whom his approval rating has remained generally high in the state.

The New York Times reports that democrat Chris Matthews will not be running against incumbent Republican Pennsylvania Senator Arlen Specter in 2010. The Times reports that "Matthews, the usually garrulous host of Hardball on MSNBC, has quietly signed a new long-term contract to remain with the cable network through the next election, signaling that he had quit entertaining any plans to run for a Senate seat.The deal is for at least four years. Financial terms were not disclosed, and neither side would confirm whether MSNBC had won a reduction in salary for the host, as it had been reported to be seeking. Previous reports put his annual salary at about $5 million."

Incumbent US Senator Arlen Specter has a new challenge in Pennsylvania: the state's shifting demographics. According to election data tabulated by Roll Call, his once reliable suburban Philadelphia base "has seen the sharpest drop in Republican registrations in the state -- numbers that collectively exceed his margin of victory over Pat Toomey in the 2004 Republican primary. . . . A simultaneous spike in Democratic enrollment likely means that moderate Republicans switched their registrations over the past four years. The result is bad math for Specter, who will likely face a more conservative GOP electorate in the 2010 primary than he did in 2004."

According to a new poll, GOP US Senator Arlen Specter from Pennsylvania may be the latest northeast Republican in danger of loosing his seat: "53% of Pennsylvanians -- and 66 percent of Republicans -- want someone to replace Specter. "Asked whether they think Specter, a Philadelphia Republican, has done his job well enough to win re-election or whether they'd prefer a 'new person' in that job, registered voters by a 53-38% said it's time to give someone else a chance, according to the poll by Susquehanna Polling and Research. 8% were undecided."

Senator Arlen Specter of Pennsylvania was one of three Republicans to support the stimulus package now making its way through Congress. His support appears to hurt him with many voters in the state, a possible problem for his 2010 reeelection effort. Tatest Rasmussen Reports survey in Pennsylvania roports that just 31% voters say are more likely to vote for Specter because of his position on the stimulus package while 40% are less likely to do so."

Pennsylvania Republican US Senator appears to be highly vulnerable in his upcoming 2010 reelection bid. When Pennsylvania voters were asked in a new Quinnipiac survey if Sen. Arlen Specter (R-PA) deserves re-election, 40% said yes while 43% said no.

According to PolitickerPA.com, Chris Matthew's brother Jim thinks the journalist and MSNBC anchor will not challenge incumbent Republican Pennsylvania Senator Arlen Specter in 2010: "'There is no hint of him running for office,' said Matthews . . . 'That's 1,000 percent true.' Jim Matthews, a Republican commissioner in Montgomery County, emphasized that it's his opinion -- he didn't hear it directly out of his brother's mouth. But he said his brother was very upbeat about returning to "Hardball" and already had a new contract offer in hand from the cable news network. I know there's been discussion about (a Senate run) ... but I would be stunned beyond words if he does anything besides but look forward tomorrow to going to work . . . I just think he's recharged.'" Yesterday, Chris Matthews echoed his brother's sentiment, telling his staff at MS NBC Hardball that he has NO intention of taking on Specter in 2010.

According to Poltico, Chris Matthews is about to sign a new contract with MSNBC News. Does this make a run in 2010 against incumbent Reoublican senator Arlen Specter less likely? Probably, since retaining his job as a political commentaor would present a conflict of interest fot the journalist.

Contradicting some recent polling that shows Chris Matthews trailing Republican incumbent Arlen Specter in a hypothetical 2010 US Senate matchup, Rasmussen Reports has released a poll indicating that the Democrat presents a real threat to Specter: "Republican Senator Arlen Specter is potentially vulnerable in his 2010 bid for re-election. A Rasmussen Reports telephone survey of Pennsylvania voters finds Specter leading MSNBC pundit Chris Matthews by just three percentage points, 46% to 43%, in a match-up that may foreshadow one of the nation's most closely-watched Senate races." More from CQ Politics on the Rasmussen poll: "The moderate Specter has only a 68 percent favorability rating in his own party but benefits from being viewed positively by 48 percent of Democrats. As far as actual support, 70 percent of Republicans say they would vote for him and 32 percent of Democrats said they would too."

According to Poltics PA, talk show host, Democrat Chris Matthews remains interested in challenging incumbent Republican US Seanator Arlen Specter in 2010: "Knowledgeable sources have confirmed that Matthews has discussed a possible run for U.S. Senate with Congressman and Philadelphia Democratic City Committee Chair Bob Brady; Treasurer-elect Rob McCord; Allegheny County Democratic Chair Jim Burn; and Neil Oxman, Pennsylvania's premier political consultant."A recent Quinnipiac University poll suggests that neither candidate would walk away with the race, but that Matthews was in a weaker position at this point. In the poll, Specter lead Matthews, 45% to 33%.

Quinnipiac is out with an early barometer of the hypothetical 2010 Us Senate match up between incumbent Republican Arlen Specter and MSNBC political commentator, Democrat Chris Matthews. The survey reports that Specter holds a 45% to 33% lead over Matthews. "Sen. Specter leads 72 - 9 percent among Republicans and 45 - 27 percent among independent voters, while Matthews leads 55 - 25 percent among Democrats." "Who says the Republicans are dead? Sen. Arlen Specter has the highest job approval rating of any major Pennsylvania Pol and would knock off Chris Matthews by 12 points if the Hardball host decides to run against him," observes (Quinnipiac assistant polling director) Clay Richards. "Matthews has been on MSNBC wall to wall during the election season, but is a question mark for 60 percent of the voters. Specter has been relatively invisible the past year and has a strong 56 percent favorable rating."
