Greg Sargent asks — is the White House bracing for and Arlen Specter loss?  Is that why Joe Biden won’t do last-minute events with Specter?

Bob Schiefer said so on the CBS Philadelphia affiliate station (video):

SCHIEFER: I’ll tell you in all candor, I have been told on background and so forth that the White House is preparing for a Specter loss here and that the President doesn’t want to be associated with that.  Now I’m not sure what kind of an on-the-record answer you’d get from the White House, but that seems to be what people are saying on background.

It may have something to do with the numbers that Quinnipiac is seeing:

The Pennsylvania Democratic Senate primary goes down to the wire with U.S. Rep. Joe Sestak taking 42 percent of likely primary voters to Sen. Arlen Specter’s 41 percent, according to a Quinnipiac University poll conducted through Sunday night and released today.

With 16 percent undecided and 25 percent of those who do back a candidate saying they might change their mind, the race is too close to call.

Looks like rain tomorrow, which would help Sestak and hurt Specter.  Specter’s voters are less motivated and thus less likely to turn out.  Also, local Pennsylvania Democratic party workers can’t switch gears and suddenly start loving the guy they’ve been fighting for the past three decades just because Ed Rendell snaps his fingers.  They are the ones who do the grunt work of turning out voters on election day.

I’d say things look pretty good for Sestak right now.
