An array of Republican heavyweights who backed Mitt Romney’s 2008 presidential bid are not yet committed to - and in some cases, downright skeptical of - the former Massachusetts governor’s all-but-certain 2012 campaign.

In each of the traditional early states, top Romney supporters from the last campaign tell POLITICO that they’re hesitant to get behind the nearest thing the GOP has to a frontrunner. His difficulties are particularly acute in Iowa and South Carolina, where his former enthusiasts say they have not heard from him, believe he may be intent on downplaying the states in his second White House run and are openly flirting with his potential rivals.

Asked specifically what Romney needed to do to earn his support again, Fmr. Sen. Judd Gregg (NH), who was a national co-chair of the Bay Stater’s bid in 2008, said flatly: “I haven’t made any decision.”
