@billybobWhy do so many people think Biden is just a shoe-in? I highly doubt that to be true, especially since by the time that would happen (after at least a few debates), it could very well be too late, even if he is the Dem wet dream so many believe to be true.
@shifty :
H e already has his ear to the ground with democrats all over the country and could easily add to an existing political infrastructure that would be needed to mount a campaign on short notice. Also, if truth be known it is quite possible that some things are on "stand by" if they are needed. Many of those contacts also come from all his years in the senate.
He has also been very well vetted from his years in the senate and as VP so there would be no surprises to complicate the situation.
