U.S. Rep. Joe Sestak continues his stretch run in the Pennsylvania U.S. Senate primary and now trails incumbent Sen. Arlen Specter by a too-close-to-call 44 – 42 percent among likely Democratic primary voters, according to a Quinnipiac University poll released today. Another 14 percent of Democrats are undecided, and 29 percent of those who name a candidate say they might change their mind. […] – Specter-Sestak Dem Primary Too Close To Call

Next week Arkansas, Kentucky (where Tea Party candidate Rand Paul is taking his fight against establishment to Mitch McConnell’s doorstep – and doing very well in the process), Oregon, with a special election in Hawaii (with Democrats in complete disarray giving Republicans a real in), and Pennsylvania hold primaries.

The DSCC is pouring funds into the race on behalf of Arlen Specter in a race that has Joe Sestak surging.

… The Specter campaign has not gone out of its way to reveal this fact. The Youtube version of the Obama ad sent out yesterday to reporters featured a disclaimer at the end indicating that the ad was being funded by the Specter campaign.

But a version of the ad that’s actually running on at least two Pennsylvania stations — sent my way by a Pennsylvania Democrat — features this disclaimer: “Paid for by the Democratic Senatorial Campaign Committee.” […]

I’ve had the pleasure of working independently on behalf of Joe Sestak back when he ran against Curt Weldon. I’ve interviewed Sestak several times, among having other interactions.

I’ve also been part of a small new media conference call with Sen. Specter, who was more open and forthcoming than I anticipated.

It’s remarkable that Sestak has closed the gap, especially since the Obama White House is working hard against him. But once Specter swiftboated Joe Sestak over his military record the negative blowback said it all.

Anything can still happen in this race, but Pres. Obama has put his credibility on the line in Pennsylvania, which in an anti-incumbent year may not be enough for Arlen Specter, who’s been around a long time as a Republican.
