The longtime Democratic senator was long considered a likely choice for vice president, but the buzz surrounding him intensified after he returned earlier this week from a two-day trip to the Republic of Georgia after Russian troops invaded.
Biden, chairman of the Senate Foreign Relations Committee, brings years of experience that could help counter GOP arguments that an Obama administration would be inexperienced on foreign policy.
Biden abandoned his own White House run after a poor showing in Iowa's first-in-the-nation caucuses. He also ran for the 1988 Democratic presidential nomination but dropped out after charges of plagiarism in a stump speech.
My general reactions to this are well known, I've blogged on Biden as a potential candidate from day one I thought he would be a great choice. With the way things have fallen into place recently, though, I think Clinton might have been a better choice. If Biden can attack McCain on foreign policy and do so tastefully, with carefully chosen words, he will be a great asset to Obama in this election.
