Reps. Todd Akin (R-Mo.) and Jason ChaffetzJason ChaffetzThe myth of the conservative bestseller Elijah Cummings, Democratic chairman and powerful Trump critic, dies at 68 House Oversight panel demands DeVos turn over personal email records MORE (R-Utah) are firm nos, according to The Hill's Whip List, while Rep.

Rep. Denny Rehberg (R-Mont.) has not yet indicated which way he will vote.


Akin faces a potentially tough primary challenge from former Missouri State Treasurer Sarah Steelman, and can't afford to give her an opening to run at him from the right.

Both parties are on the attack over the issue. Missouri Democratic Party spokeswoman Caitlin Legacki pointed out that Sen. John McCainJohn Sidney McCainBiden eyeing Cindy McCain for UK ambassador position: report The Memo: GOP mulls its future after Trump Juan Williams: Obama's dire warnings about right-wing media MORE (R-Ariz.) had described the "cut, cap and balance" approach to raising the debt ceiling favored by both Akin and Steelman "bizarre" and "foolish," and ripped them for their positions.

"If there were any questions whether Sarah Steelman and Todd Akin are too extreme for Missouri’s middle class families, this should remove all doubt," said Legacki in a statement. "Rather than supporting commonsense ideas and reasonable compromise, Steelman and Akin would rather play chicken with the economy to score political points. That’s not leadership, that’s recklessness."

The National Republican Senatorial Committee also attacked McCaskill for opposing BoehnerJohn Andrew BoehnerPrinciples to unify America Feehery: A possible House Speaker conundrum for Democrats Obama on bipartisanship: 'There is a way to reach out and not be a sap' MORE's plan. "In yet another sign that she’s prepared to put the reelection efforts of herself and President Obama ahead of avoiding the federal government defaulting on its debt for the first time in U.S. history, U.S. Sen. Claire McCaskill joined with her liberal party leaders last night in signing a letter announcing her firm opposition to the two-step plan offered by House Speaker John Boehner which will be voted on by the House later today," NRSC communications director Brian Walsh wrote in an email Thursday morning.

Senate race politics could also be playing a part in other House members' decisions. Chaffetz is all but certain to challenge longtime incumbent Sen.

Flake has long been a crusader for fiscal conservatism, but has a political reason to oppose the plan as well: he has already lost favor with some Arizona conservatives because of past centrist votes in immigration, and while he doesn't yet have a primary challenger, a vote for this plan could invite one.

The four also don't have to fear Boehner's wrath in the same way that other Republican House members do, since they won't be around much longer, meaning that the GOP leadership can't leverage their votes in the same way it could others.
