Yeah, what about Romney's VP pick?

Two Mondays ago, there was word that he "might make the announcement by the end of the week". The end of that week and the week after have come and gone, and now he avoids the question whenever he's asked.

So what is he waiting for? Is it Tim Pawlenty? Rob Portman? Marco Rubio?

I think that Romney is delaying the announcement and avoiding the question because he's asked all the A-list Republicans on his list, and they've all said "no".
