The latest WaPo/ABC News poll finds that Romney's unfavorables have spiked:
Among independents, Romney’s unfavorable rating now tops 50 percent — albeit by a single point — a first in Post-ABC polling back to 2006. Just two weeks ago, more independents had favorable than unfavorable views of Romney; now, it’s 2 to 1 negative.
Chait thinks this poll damages Romney's primary argument for his candidacy, that he is the most electable candidate:
The Obama campaign would almost certainly still prefer to run against Gingrich. But the electability gap between the two leading contenders is dwindling. No wonder more and more conservatives are frantically casting about for a new candidate to jump in and save the day.
