Lieberman says he won’t rule out running as a Republican in 2012.

liebsIn 2006, Sen. Joe Lieberman (I-CT) was defeated in his Democratic primary by insurgent challenger Ned Lamont, largely due to Lieberman’s unyielding support for the Iraq war. After forming the independent “Connecticut for Lieberman” Party, Lieberman ran as an independent and went on to defeat Lamont in the general election. In an interview with CNN yesterday, Lieberman said he’s “unsure” which party’s ticket he will run on in 2012, and even left the door open to running as a Republican:

Independent Sen. Joe Lieberman, a former Democrat who sits with Democratic caucus, said Tuesday that he would not rule out running for re-election in 2012 as a Republican. Lieberman angered his colleagues in the Democratic caucus this week by threatening to torpedo health care legislation if it contains a government-run public health insurance or an expansion of Medicare.

Lieberman said he wasn’t sure which party, if any, he would represent in his next election.”I like being an independent, so that’s definitely a possibility,” the Connecticut senator said. “But I’d say all options are open.” He called running as a Republican “unlikely” but added that he wouldn’t “foreclose any possibility.”

Former Sen. Lowell Weicker, who Lieberman defeated in the 1970s, was interviewed about his former rival. “He was basically elected as a Republican when he lost the Democratic primary,” Weicker said. “It was the Republicans who put him into office. Yes, I am an independent. I don’t think Sen. Lieberman is an independent.”
