After independents supported President Obama in 2008, the pendulum has swung toward Republicans in 2010: CNN polling earlier this month showed 62 percent of independents backign the GOP in the coming midterms, while Pew polling today shows a less drastic advantage, with the GOP winning independents 49 - 63 percent.

But what's even more encouraging for Republicans is the enthusiasm gap among independents, as the GOP supporters are more engaged.

From Pew's findings:

Uncharacteristically, independent voters, who typically are not highly engaged by midterm elections, are now more likely than Democrats to say they are giving a lot of thought to this election. The relatively high level of independent engagement this year has come among those who plan to vote Republican. Fully 64% of independents who plan to vote for the Republican in their district are giving a lot of thought to the election, compared with just 40% of independents who plan to vote for a Democrat.
