May have waited too long to make this prediction. I posted the reasons on WikiAnswers about a week ago.
Recapping, here's why... Gov. Ed Rendell will BE the Vice Presidential nominee.
He of all the name office-holders best serves the most compelling of the Obama campaigns needs. Besides bagging PENNSYLVANIA, he is
1)The least objectionable and probably closest FOB and FOH of the prospects
2)The best demographic fit with OHIO voters
3) Jewish, offering Obama a huge leg up in FLA.
4) He is a middle-class "lunch bucket" moderate who is the former Chairman of the DNC (Unity, unity, unity)
5) His strength is pocketbook domestic issues (bucked Unions and instituted an Rx program in Penn), i.e. he helps most with white middle-class men.
6) His lack of national foreign policy experience is preferrable to being out of touch with working-class white men in an election that will turn on a souring economy.
7) He blows the 'elitist' label out of the water. Particularly if McCain chooses Romney.
8) His having been kept out of the national limelight will make his choice seem an energizing stroke of genius. Which is probably why the 3 dwarves (Kaine, Bayh and Biden) have been so publicly paraded.
RICHARDSON is the other, even greater choice, but the Clintons have probably vetoed his nomination, refusing to let will him to be rewarded for what they regard as his treachery.
