Yesterday on Meet the Press Chuck Todd suggested Putin's invasion of Georgia may have an impact on Barack Obama's choice of Vice President:

MR. TODD: I think that's right. And you almost wonder if did Vladimir Putin suddenly become on the vetting list a little bit for--is he joined Eric Holder and Caroline Kennedy and eliminated Tim Kaine.

MR. GREGORY: He apparently wants to stay in politics.

MR. TODD: Yeah, exactly. But no, but Putin, Putin's decision, you know, to cause this uproar in Georgia was just a reminder that during the campaign something of foreign policy nature could pop up, and while Obama's very confident, I think that's why Tim Kaine's out.

Add to that news this morning that Pervez Musharraf is resigning, and you have to wonder whether developments overseas aren't driving Obama in the direction of Evan Bayh or Joe Biden.
