In May, the conservative blog Redstate posted a story wondering, "Could a Romney/Petraeus Ticket Be a Game Changer?" The story noted that the onetime four-star Army general, Princeton PhD and commander of allied forces is well-respected and seen as above politics; "Additionally," it continued, "Petraeus would bring foreign policy expertise to the ticket, balancing Romney's focus on economic issues." Petraeus says he stopped voting in 2002, but he is registered as a Republican.

Why he won't be picked: For starters, he's currently the Director of the Central Intelligence Agency under President Obama - and abruptly stepping down from that position to join Romney's ticket would undercut his reputation as putting country before politics. In addition, his national security credentials would move the focus in the race away from the economy, the issue Romney clearly wants to talk about. And then there's Petraeus' repeated avowal that he will never run for public office: In Manchester, N.H., in March 2010, he noted he's said "no" many times.

"I feel very privileged to be able to serve our country," he said. "I'm honored to continue to do that as long as I can contribute, but I will not, ever, run for political office, I can assure you. And again, we have said that repeatedly and I'm hoping that people realize at a certain point you say it so many times that you could never flip, and start your career by flip-flopping into it."
