Biden the probable Veep Pick, sources say

Within the last few hours I've spoken with two of the finalists for the role of Barack Obama's running-mate, and to two other sources who are close to the process.

My bottom line is this: Barring a big surprise or last-minute change of heart, the choice is likely to be Sen. Joe Biden of Delaware, chairman of the Foreign Relations Committee.

He is a lively and feisty if unpredictable campaigner with working-class roots and a street-level feel for the hot spots of the globe — which he can use to go toe-to-toe with Sen. John McCain.

"If I had to bet my life on it, I'd bet it is Joe," said one of the other contenders.

Said another, "Barack is moving toward a seasoned Beltway type, and that probably means Biden."
