Campaigning for Specter? Is Obama serious?
That would be the most disgusting thing I've ever seen. Talk about stooping into the pigsty. And, no, it is not "smart" for 'bama to do so. It is disgusting and it is insulting to the people of PA...who have shown themselves to be remarkably unforgiving of this sort of crap (see: all members of the state education board being voted out after voting to err on the side of the creationists).
And although it WOULD be gross if he did campaign for the ol' bag, it would also prove beyond a shadow of a doubt that Congress is just a bunch of hats being passed around... and THAT would tickle my told-you-so bone a bit. Tee-hee.
