The Weekly Standard sez:

According to (our) source in Pennsylvania, the DSCC has purchased TV ads for the coming week only in the Pittsburgh media market, where Democrats are facing particularly bad poll numbers. Pro-Toomey groups will be heavily outspending Sestak and Senate Democrats this week, says our source: "Sestak plus DSCC is smaller in every market, except Pittsburgh, than Toomey plus the Club for Growth plus American Crossroads."

The DSCC's nearly $3 million ad campaign over the past five weeks hasn't done much to budge poll numbers in the Keystone state. According to the RealClearPolitics average of polls, Toomey's lead over Sestak has been fairly stable during that time, with Toomey holding anywhere from a 6 to 8 point lead over Sestak. Toomey's current lead over Sestak in the RCP average of polls is 6.5 points.

But that's down a couple of percentage points from the last couple of weeks. I think Joe's negative ads tying Toomey to Wall Street may be working. The Dems would be dumb to give up on this race. But then the Dems have been dumb about a lot of things lately.
