From the latest Gallup Poll:
55% of likely voters in Gallup's Oct. 14-24, 2010, polling are Republicans and independents who lean Republican. This is higher than the Republican showing in the past four midterm elections, although not too dissimilar to the 51% found in 2002. The corollary of this is that the 40% of likely voters now identifying as Democratic is the lowest such percentage of the past several midterms.Click here to read the full report from Gallup.
Notably, this year's high Republican representation among likely voters stems mainly from a substantial increase in Republican-leaning independents in the likely voter pool -- now at 16% -- reflecting the broader shift toward the Republican Party among independents evident since 2009. . . .
Gallup's recent tracking of the generic ballot for Congress has shown the Republicans with substantial leads over the Democrats among likely voters, in part because the underlying registered voter population leans Republican in its vote choice. Compared with previous elections, that tilt is an extraordinary positioning for the Republicans, who typically do no better than tie the Democrats among registered voters. The GOP's position is further enhanced by the generally strong proclivity of Republicans to turn out to vote, which appears to be even greater than usual this year.
