Arlen Specter's numbers against ex-Rep. Pat Toomey haven't changed much from October, which isn't good news. What has changed here is that, unlike October, where Rep. Joe Sestak led Toomey by a point, Sestak now trails Toomey by 6, making it harder for Sestak to make the argument he'll perform better vis-a-vis Toomey. Specter's numbers are pretty locked-in, though, with only 6% of all voters having no opinion of him, compared with 19% for Toomey and 26% for Sestak.
On the Democratic primary front, the single-digit gap between Specter and Sestak from October (the smallest yet seen in the race) is back to 13. Specter actually has pretty good approvals among Dems, maybe thanks to his race to the left (66/25). Sestak is at 48/22, but that leaves 25% not sure, giving him a lot more of a ceiling for growth.
