Gregg is retiring and will vote in favor of the plan, while Coburn, who is not running for reelection, and Crapo signaled Wednesday that they may vote in favor to keep the deficit debate going.
The commission will not get 14 votes, in part because incumbent GOP congressmen and senators who have signed the pledge will not support the tax hike plan.
