Persuadable Voters: How Much Of A Factor?
Posted Oct 21, 2008 at 12:54 PM by Maurice Berger
With one tracking poll this morning showing the race virtually tied (GWU/Battleground: 48% to 47%, +1 DEM) and another showing the Democrat with a healthy lead of +8%--and the latter, Reuters/C-SPAN/Zogby, leaping from a virtual tie on Monday--it looks like things are a bit fluid right now. What might account for these differences? For one variations in likely voter models and other statistical markers and methods. For another: persuadable voters. As PollTrack has been reporting, certain voters account for about 85% of the electorate right now, according to most polls. A small number more are undecided or are voting for third party candidates. The lion's share of those remaining, the roughly 12% of the electorate who are "persuadable," say they could change their minds. This effect is registering in some of battleground state polls as well. Here is the Concord Monitor/Research 2000 analysis of its most recent polling in New Hampshire: "Obama has solidified his support, according to the poll, with 45 percent of those polled proclaiming themselves "firm" in supporting the Illinois senator. McCain, an Arizona senator, garnered the firm backing of 40 percent of those polled. Still, 15 percent of those polled said they could change their minds, leaving the race still fluid with two weeks to go before Election Day." Indeed, the day before the New Hampshire Democratic primary, Obama had an average lead of +8.0%. What no media outlet noticed (except PollTrack, though you'll have to take our word on this): the large number of persuadable voters still in play less than 24 hours before the vote. And, of course, Hillary Clinton went on to win the state. Will persuadable voters produce an election day surprise? Or will they continue to break for Obama (leaners now favor him by a small margin), thus assuring him a solid win? Let's take a look at the persuadable numbers a few days before the election.
