Party On

He had a substantial lead not long ago, but now senator Arlen Specter is running behind his challenger in the Democratic primary.

PA's Congressman Joe Sestak has taken a five point lead over the old vanguard of Senator Arlen Specter in Pennsylvania's Democratic primary, according to polling done by Rasmussen.
You'll recall that Specter switched parties last year, sure that he would be knocked off in the GOP primary by Pat Toomey.
Sestak’s candidacy is helped by the anti-incumbent mood sweeping the country, evidenced by Sen. Bob Bennett’s (R) defeat in Utah over the weekend. How much will the White House help Specter in the coming days? Obama’s selection of Elena Kagan did not help Specter, who voted against her nomination as solicitor general when he was a Republican.
A Sestak triumph would be seen as a bit of a rebuke of the president’s endorsement of Specter, though Obama would quickly endorse Sestak in the general election.
Still, Sestak’s gun-control stance could hurt him against Toomey in the general. First things first. Sestak has to show he can finish off the wily Specter, who probably has a few tricks up his sleeve.

It's so much fun when they get to the vicious stage of a close election!
