Savage conceded that Romney is “not as strong a conservative as many would like him to be,” but listed the reasons why he thinks Gingrich is a threat to Republicans.

Savage said that as Speaker of the House, Gingrich didn’t deliver on his “Contract with America.” He also cited the ad Gingrich made with Rep. Nancy Pelosi (D-Calif.) about global warming, which Gingrich has called the "dumbest" move of his career, and said Gingrich’s idea to offer illegal aliens who are established in the U.S. a path to citizenship amounted to “amnesty.”

In addition, Savage noted Gingrich’s ties to mortgage giant Freddie Mac, his failed marriages and infidelity, and his remark that Paul RyanPaul Davis RyanThe Hill's Morning Report - Presented by Emergent BioSolutions - Facebook upholds Trump ban; GOP leaders back Stefanik to replace Cheney Budowsky: Liz Cheney vs. conservatives in name only Cheney at donor retreat says Trump's actions 'a line that cannot be crossed': report MORE’s budget plan amounted to “right-wing social engineering.”

Some have argued that Gingrich’s prowess as a debater would pit him well against President Obama during the election, but Savage said that regardless of how well he does, he will “come off badly compared to Obama and look like nothing more than what he is: a fat, old, white man.”

“If Newt Gingrich really loves this country as much as he says he does, if he really wants what is best for America, he will set his ego aside, call me, and accept my offer,” the statement said. “His continued candidacy spells nothing but ruin for conservatives, Republicans and all true American patriots. One million dollars in exchange for preserving the nation, Newt. I say take the money and don’t run.”
