ROANOKE, Va. – Warming up a crowd for Democratic presidential hopeful Barack Obama in the Blue Ridge mountain region of Virginia, Sen. Jim Webb on Friday took aim at Republican vice presidential pick Sarah Palin’s qualifications.

Webb, who has deep roots in the Appalachian region, invoked a popular country music song about a romantic encounter gone bad to suggest that John McCain may regret his selection of the Alaska governor as his running mate.

Then he asked rhetorically, “What is the one decision that a candidate makes before he or she is elected that clearly indicates what their judgment is?”

Webb responded that it was the pick of a running mate and went on to laud Obama’s choice of Delaware Sen. Joe Biden as his No. 2.
