Rep. Michele Bachmann (R-Minn.) told voters in Iowa on Monday that Congressional Republicans backed down too easily in the recent budget fight, saying, "We will never win if we don't fight."

Bachmann has been an outspoken critic of the deal struck by Congressional leaders and the White House late last week. The rumored 2012 presidential candidate has said she won't vote for the long-term budget deal because it doesn't defund the healthcare law.

"We're the ones who decide how the money gets spent," Bachmann said during an event Monday, according to Radio Iowa. "And Barack Obama gets no money, zero money unless we give it to him, and so he can be held hostage and Harry Reid can be held hostage if we don't give them money."

Bachmann urged lawmakers to be willing to risk "a government slowdown" in future budget battles.

A handful of other rumored 2012 presidential hopefuls called the budget deal a step in the right direction. Over the weekend in South Carolina, former House Speaker Newt Gingrich (R-Ga.), former Sen. Rick Santorum (R-Pa.) and Mississippi Gov. Haley Barbour (R) all expressed some level of support for the agreement. Former Arkansas Gov. Mike Huckabee (R) also labeled the agreement a partial victory on the road to the battle over Rep. Paul Ryan's (R-Wis.) proposed budget.

Former Alaska Gov. Sarah Palin (R), meanwhile, was critical of the budget deal, saying it fell too far short of the cuts Tea Party activists were hoping for. 

Bachmann was in Iowa for two speeches Monday as party of The Family Leader's "presidential lecture series." The social conservative group is headed by former Iowa gubernatorial candidate Bob Vander Plaats, a key broker in the state's Evangelical community who has said he's likely to endorse a candidate before next year's Iowa Caucus.
