Interesting. I would have said after election 2012 that there's no chance Romney will run again, he's made it quite clear. But now I'm not so sure. In the 2 years after Romney's run, it has been proven that he was right on a number of issues including, Iraq, Russia, Putin, the economy and a quite few others. Plus, a CNN Poll released yesterday showed if the election were held today, Romney defeats Obama 53-44.
So maybe he's thinking of changing his mind. There were also a couple of polls that showed Romney leading in New Hampshire in the GOP primary if he were to run in 2016
