This is pretty striking:
Exit polls showed independents supporting the GOP by a 19 point margin last year at 56-37. Now only 30% of those voters think that the Republican controlled House is moving things in the right direction, compared to 44% who think things were better with the Democrats. Given those numbers it's not much of a surprise that independents now say they'd vote Democratic for the House by a 42-33 margin if there was an election today, representing a 28 point reversal in a span of just five months.
We're in very fluid times – as befits a country facing a debt meltdown. And Obama is a nimble swimmer.
