Mitt Romney will sign DeMint's 'Cut, Cap and Balance' pledge

Former Massachusetts Gov. Mitt Romney (R) will become the latest signatory to a pledge being promoted by Sen. Jim DeMint (R-S.C.) as a litmus test for presidential candidates.

Romney indicated on Capitol Hill that he's a supporter of the new "Cut, Cap and Balance" pledge, and his campaign confirmed Wednesday that he intends to sign it.

Romney's name means that Rep. Michele Bachmann (R-Minn.) is the only announced presidential candidate not to have signed it aside from former Ambassador to China Jon Huntsman (R), who has sworn off all pledges.

Bachmann said Monday that she'd spoken with DeMint on Friday and is evaluating the pledge.

"I'm looking currently at the Cut, Cap and Balance program. I was on the phone with Sen. Jim DeMint from South Carolina last Friday," she said on Fox News.

The pledge is to oppose any raising of the debt ceiling until there are deficit-reducing spending cuts, enforceable caps on federal spending and congressional passage of a balanced budget amendment.

Romney's decision to sign underscores DeMint's role as an influential figure poised to shape the Republican campaign, if not as a candidate. DeMint has said he wouldn't endorse any figure who doesn't sign the pledge, and he's already ruled out backing Huntsman.

Romney's been somewhat skittish about signing onto pledges. He signed Grover Norquist's "Taxpayer Protection Pledge" last week, but passed on signing an anti-abortion rights one crafted by the Susan B. Anthony List. Romney's campaign said that pledge was overly broad and could have unintended consequences.

DeMint backed Romney for president in 2008, but hasn't been as eager to sign on this time, citing the healthcare law Romney signed as governor as a potential stumbling block. After having originally allowed Romney some wiggle room, a DeMint ally clarified by emphasizing that Romney wouldn't win an endorsement without repudiating the healthcare law in Massachusetts.

After Romney stood by his plan at a speech in Ann Arbor, Mich., in May, DeMint still said he wouldn't rule out backing Romney again in 2012.
