Daily tracking poll shows Joe Sestak and Arlen Specter are tied at 43% apiece. It's now "on"..

I was wondering how effective this new ad that Joe Sestak was running would be against Arlen Specter. Well, apparently pretty darn gosh effective.

Here's that ad:

Here's some excited analysis from Open Left's Chris Bowers:

Pennsylvania Senate--Sestak and Specter tied: This morning's tracking poll shows Arlen Specter and Joe Sestak tied at 43%. The tracking poll is a four-day rolling average, and so it does not even include many interviews who have seen Sestak's devastating new attack ad. I don't want to get ahead of myself here, but with 11 days to go, for all the reasons I discussed yesterday, Sestak may actually be the favorite now. Specter is hovering around 45% in the polling average, which is a very bad place to be for a candidate with nearly 100% name ID. Sestak still has a lot of room to grow in terms of name recognition, and has always led among Pennsylvania voters who knew both candidates.

Related: Don't forget Joe Sestak also has some excellent Internet only "Why We Fight" ads. I kind of wish he would run these occassionally on television as well. They're very effective.
