House Speaker John Boehner (R-Ohio) will have the votes to pass his debt-ceiling-increase proposal through the House of Representatives, Sen. Mike Crapo (R-Idaho) said.

"It looks like they are going to have the votes to get it through. I’m guessing it will be a close vote, but I believe Speaker Boehner will ultimately be able to get the votes necessary to pass that plan," Crapo said Wednesday on Fox Business Network.

Since Boehner unveiled a divided Republican Caucus in the House, some Republicans have said they won't vote for the plan, instead advocating for Republicans' "cut, cap, and balance" plan.

But over the past few days an increasing number of Republicans have signed on to or indicated they would likely vote yes on his proposal, which raises the debt ceiling by $900 billion and cuts federal spending by an equal or larger amount.

Democrats have vowed that the plan is dead on arrival in the Senate and won't make it to President Obama's desk, where he is likely to veto the measure.

On Wednesday, Rep. Frank Guinta (R-N.H.) was optimistic though that Boehner's plan would eventually become law.

"Yeah, I've taken a look at the Boehner package and, you know, right now this is about what can we establish in short- and long-term cuts in order to raise the debt ceiling," Guinta said.
