Obama’s Veep Trial Balloons

Two weeks ago it was – STOP THE PRESSES!!! – Tim Kaine. Last week it was Bayh, Bayh, Bayh. This week’s flavor is Biden, strengthened by his trip to Georgia at Saakashvili’s request. Anyone notice that camp Obama has been floating trial balloons on all of these veep wannabes, quietly trying them on for size in the press? So what does this tell us? Only that the three are leading candidates who have been vetted and taken out for a test drive. And some time before Aug. 28 we’ll know which one was the best ride, or at least the less bumpy.
