Washington (CNN) - Connecticut Sen. Joe Lieberman told CNN Tuesday that he has not ruled out running as a Republican in 2012.
Lieberman told CNN Senior Congressional Correspondent Dana Bash Tuesday that the move remained a legitimate, if unlikely, option. "I don't know what I'll run as," he said. "I like being an independent. So that's definitely a possibility. But I'd say all options are open….
"It's unlikely I'd run as a Republican, but I wouldn't foreclose any possibility. I think the more likely thing is that I'd run as an independent because that's what I am."
He also denied that a decision on whether to caucus with Republicans depended on which party was in the majority: "Well, no. It depends on where I am. That's all hypothetical. I'm just happy to be where I am. I'm grateful I got reelected in '06, and I'm going to try to do the best I can every day.
"I've reached the stage in my career where I'm not measuring every step I take based on how it's going to affect the next election. I think if you do that you end up compromising the quality of your service."
"In this very polarized time in our politics, if you take a stand, a bunch of people will think you've done something great and a bunch of people will think you've done something awful. You've got to decide, I've got to decide that I've done the best I could to do what's right and best for my country and my state. And that's what I feel I'm doing on health care reform."
