Now, the rest of the story: This is just the latest high-profile move by Romney since he dropped out of the race on Feb. 7th. His campaigning on behalf of presumptive GOP nominee John McCain – and his promise to raise $15 million for the presidential run of a man who he once suggested was similar to Hillary Clinton and Barack Obama on key issues – has prompted speculation that Romney running for vice president.

Romney boosters suggest that the former venture capitalist could shore up McCain's economic bona fides as the country enters a difficult economic period, but a group of social conservatives have launched an effort to keep Romney off the ticket for being insufficiently socially conservative.*

*CORRECTION: This post initially stated that former Romney supporter and conservative leader Paul Weyrich was behind the “NoMitt” campaign. Weyrich was merely one of those listed as backing the initiative, and he released a statement this week asking that his "involvement in this effort be disregarded." You can read it here.
