I came to Biden only through the realization that this is already the dirtiest GOP campaign in history (and that's saying a lot) and Obama needs someone who can help him fight it more than any other consideration.
I've avoided up till now of naming a favorite (I don't have one) or guessing who will be chosen. But with McSmear diving deeper into the sewer with each passing day, I think Obama's prime consideration is someone who can cover his back and be a surrogate to hurl the garbage back into McSmears face.
And Biden fits that job description better than any I can think of. He had the disadvantage of having voted to invade Iraq along with McSame, but with the Bushit Regime about to announce a deal with Iraq that includes a timeline for withdrawl, Iraq will become a secondary issue anyway -- except that Obama will be able to say, "I told ya so -- yet again."
So bring on the shit McMud, and Obama will have just the person to make you eat it yourself.
I think you're just one of those people who absorbs propaganda like a sponge and then squeezes it back out on demand. You'll be denouncing Obama (even as you support him ) next, based on what you read on blogs.
