In National Journal Magazine, Charlie Cook writes about the shift in public opinion of Republican candidates in the The Cook Report

Republican pollster Glen Bolger, who worked on the survey for Public Opinion Strategies, says that this is the first time since 2004 that he has seen independents favoring Republicans on the generic ballot test. Although he concedes that poll participants agreed — by margins of 6 to 11 points — with Democrats more than Republicans on each of the issues tested, he contends that the generic question’s results are “evidence that voters, particularly independents, are worried that they overcorrected in the 2006/2008 elections combined, and now have more of a liberal slant to government than they want. They want change but with checks and balances.”
