"Boehner had a litmus test list created to target conservatives who don't vote with leadership. That's not what the GOP is about. This intransparent list has enraged our base to find more open, more articulate leadership," Ryun said.
Boehner's office did not respond to requests for comment regarding this story.
A body of powerful House Republicans still remain unaffected by the committee maneuvering, and has signaled they will stand behind Boehner to avoid going over the fiscal cliff. Even past rivals, including Majority Leader Eric Cantor have voiced support for Boehner's latest package, which lays out $2.2 trillion in deficit saving and $800 billion generated from reforming the tax code. House Budget Committee Chairman, Wisconsin Rep. Paul Ryan, also endorsed Boehner's plan.
