Sen. Joe Lieberman (I-Conn.) said he's likely to pursue reelection as an Independent, if he decides to run again at all.

Lieberman, who was reelected in 2006 as an Independent after having lost his state's Democratic primary, said he hadn't made any decisions about whether to run again, or whether he'd run as a candidate in either party.

"I'd say right now if I run again, it's more likely I'll run as an Independent," Lieberman said Friday on MSNBC.

The Connecticut senator has caucused with Democrats since beating challengers from both parties in the 2006 general election, though he angered many Democrats by campaigning for Sen. John McCain (R-Ariz.) in 2008's presidential election.

Since then, Lieberman has faced entreaties from both parties as he mulls his path forward. Sen. Patty Murray (Wash.), Senate Democrats' 2012 campaign chief, has made it known that she wants to sit down and talk reelection with Lieberman.

But Lieberman said that he hadn't necessarily made the formal decision to seek another term, though he's generally seen as likely to pursue reelection.

"I've got a couple of decisions to make, and they're important ones me and my family have to make," he said, adding that the decisions are whether to run again and, if so, how he wants to run.

"I guess I'd say all options are open," Lieberman said. He also said he would likely announce his intentions early next year.
