It's weird that Romney decided to draw a line on this story:

"There was a story that originated today apparently at ABC based upon reports of supposedly outside unnamed advisers of mine," Romney said in Holland, Michigan. "I can't imagine who such people are. But I can tell you this: they know nothing about the vice presidential selection or evaluation process. There are only two people in this country who know who are being vetted and who are not: And that's Beth myers and myself. And I know Beth well. She doesn't talk to anybody. The story was entirely false. Marco Rubio is being thoroughly vetted as part of our process."

He usually doesn't give a damn about what the media thinks or says, and he generally keeps a very tight ship. Was it the suggestion that his campaign has a leak? Was it a behind-the-scenes fight over the fact that Rubio's memoir was released today and the junior senator from Florida needs the speculation to continue to push book sales? Did Romney just suddenly start caring about what the press thinks? Or is he really going to pick Rubio and so didn't want to seem like he was pushed into it by the media in a bit of reverse psychology?

Whatever. I still think the Republican ticket is probably going to be a pair of dull honkies when all is said and done.
