Former House Speaker Newt Gingrich (R-Ga.) named a former conservative Democratic senator as a co-chairman of his 2012 presidential campaign.

Gingrich named former Georgia Sen. Zell Miller (D) and Georgia Gov. Sonny Perdue (R) as co-chairmen of his campaign, and announced that current Georgia Gov. Nathan Deal (R) will lead the former Speaker's campaign in the state.

"I’m proud to have three very important Georgians helping lead our campaign,” Gingrich said in a statement. “Sonny, Zell and Nathan are good friends and have always provided good counsel."

Miller was elected as governor in the 1990s and to a single term in the Senate in 2000, during which time he identified himself as a Democrat. But for all intents and purposes, he served as an ideological Republican by the time he left office.

In particular, Miller made waves with a sassy speech at 2004's Republican National Convention, when he supported President George W. Bush's reelection and openly mocked the Democratic nominee, Sen. John Kerry (Mass.).

“Newt is a leader,” Miller said. “Newt’s election as president is critical to the future of our country.  We need a leader who has proven they can make big things happen.  You don’t do big things by being a wall flower.”

The choice of Perdue and Deal is also indicative of the Georgia roots Gingrich has sought to stress during the early stages of his campaign. Gingrich represented a seat in the Peach State during his time in Congress, and has locked up endorsements for his presidential campaign from most of the Republican members of the current delegation.
