All the time. In fact, he has been out campaigning for McCain/Palin and other conservative candidates non stop the past few months.
The rumors are from a few malcontents who fear a McCain loss and are trying to cut Mitt off from 2012. It's a shame people are so quick to believe gossip about others.
Thank you for your input. I have no doubt Romney is hedging his bets, playing the political game, so to speak. He doesn’t want to say too much for Palin, nor too much against her. First and foremost, Romney IS a politician. One of the reasons I was very wary of him in the first place.
