Yesterday a Suffolk poll showed Joe Sestak up 9 points over Sen. Arlen Specter in the Pennsylvania Democratic primary. Today, a Muhlenberg College tracking poll shows Specter leading Sestak by 2 points. So how's it all going to shake out in Tuesday's primary?

I think Specter will lose. With Obama refusing to stump for Specter in the final week of the campaign, polls showing Sestak faring better than Specter against Republican candidate Pat Toomey, and Sestak's further-left record, I think the choice for Democrats is clear.
