From NBC's Domenico Montanaro
Asked by NBC's Andrea Mitchell on MSNBC this afternoon if he would accept being vice president if asked, Sen. Evan Bayh (D-IN) said, in part, It's not something you turn down. "The answer to that is 'Yes,'" he said.

VIDEO: Speaking with NBC's Andrea Mitchell, Sen. Evan Bayh says he would accept an invitation to join the Obama ticket.

When asked if he was being vetted by the Obama campaign, he didn't say no, and, in fact, intimated that he is being vetted.

*** UPDATE *** Here's the exchange:
MITCHELL: Let me ask you the question that Brian Williams asked Joe Biden on Sunday on Meet the Press, if asked, would you serve, vice president?

BAYH: I don't think it's the kind of thing you say no to, Andrea. The answer to that is yes. I love my day job. I'm not looking to change, but if someone who will be leading the country comes to you and says I need your help. I want you to do this. Of course. If you care about serving your country that is the kind of thing that you do.

AM: And has the vetting begun?

EB: Well, I can't talk about that as you can appreciate, otherwise I disqualify myself from consideration [smiles]. But they have a process. That process should go forward. And we'll just see where it leads, and it's Sen. Obama's decision to make and his alone, and I think he's the one that should be allowed to speak about these kinds of things.

AM: I'm going to take that as a yes -- (EB laughs) Senator, let me just add it all up: red state, Indiana; Armed Services Committee; broad record on economic issues; foreign policy experience; former governor. Not a bad resume.
 
EB:  You're sounding like Sus---
 
AM: I can say it, you don't have to-- (EB laughs)
 
EB: I'd be immodest if I agreed with you, Andrea. Look, this country-- This is a big stakes election. We have major challenges. Particularly the middle class economic challenges that face our country. Barack Obama is dedicated to addressing those issues; to making the progress and the change the American people deserve. And I'll help him in any way I can. I'm in the United States Senate now. I'm happy to help. And we should all have that same attitude, I think.
