Former House Speaker Newt Gingrich, who led Republicans through two government shutdowns in the 1990s, says it’s clear that House Republicans want to have a “very serious collision” with President Obama about spending, the debt limit and defunding Obamacare.

“And I think the (Republican) conference believes that this is not a dictatorship. We don’t have to automatically do exactly what the president wants,” Gingrich told CNN’s Wolf Blitzer on Wednesday. “[T]he president of the United States has an obligation to negotiate,” Gingrich added later.

House Speaker John Boehner (R-Ohio) announced on Wednesday that the House will pass a continuing resolution that funds all government operations except for Obamacare. Democrats say they will not pass such a  measure; and if legislation funding the government doesn’t pass by the end of the fiscal year, the government will shut down on Oct. 1.

Gingrich said  Boehner needs to “set up the fight in the best possible way, recognizing that he’s going to have substantial elements against him, but emphasizing that he wants to keep the government open, that he wants to help the economy create jobs but that there are significant things that the president simply has to negotiate over.”
