House Budget Chairman Paul Ryan's budget is once again under fire -- this time from the right.

Rep. Paul Broun (R-Ga.), a member of the House Tea Party Caucus, has a New York Times op-ed out Tuesday criticizing the plan for not cutting more spending.

"It fails to seriously address runaway government spending, the most pressing problem facing our nation," Broun writes. "I cannot vote for something that would trick the American people into thinking that Congress is fixing Washington’s spending problem, when in actuality we’d just be allowing it to continue without end."

Ryan's budget cuts $4.6 trillion from projected spending over the next decade. Using tax increases passed as part of the "fiscal cliff" deal in January, Ryan projects a small surplus by 2023.

To achieve more dramatic cuts, Broun proposes eliminating the departments of energy and education.

The American Action Network, a center-right outside group, responded to the op-ed with a backhanded compliment, suggesting that Broun's opposition proved that Ryan's ideas were hardly radical:

Bruon first announced his opposition to the budget in a brief statement on Friday. An outspoken conservative, Broun is running for Senate on a message of fiscal restraint.

“I’ll be the only candidate in this race whose first priority is to stop the runaway spending in Washington D.C.,” he said in announcing his bid.

Should he manage to win the Republican primary, he would become a headache for the party. Even in a state as red as Georgia, Broun's history of controversial statements could give Democrats an opening.
