Specter got more votes than John Kerry in PA. There were over 150,000 people who voted for Kerry and Specter. None of those people would have voted for Pat Toomey. Arlen Specter is arguably the most popluar politician in Pennsylavnia. It sucks, but that's the truth.
These votes were from the Union-bots. The AFL-CIO endorsed Specter over Hoeffel.
That is the truth. I have relatives that really like him and many of them are democrats. Sphincter once replied personally by mail to one of my aunts years ago and took care of a phone company harassing her.
