Sen. Joe Lieberman (ID-Conn.) may face a difficult reelection battle in 2012, according to a new poll released Friday.

48 percent of Connecticut voters said they would like to see Lieberman replaced as their Senator, according to a Research 2000 poll conducted for Daily Kos. 35 percent of voters said Lieberman deserved reelection, while 18 percent said they might consider someone beside Lieberman.

Another ominous sign, 61 percent of Connecticut voters said they disapproved of the way Lieberman is handling his job, up from 43 percent in an early July poll. 36 percent said they approved of Lieberman's performance.

The poll, conducted November 11-13, has a four percent margin of error.

Lieberman lost the 2006 Democratic primary to Ned Lamont, but went on to win the general election, returning to the Senate as an "independent Democrat." Whether or not Lieberman will continue to caucus with Democrats or be lured away by Republicans has been a major topic of discussion in D.C. as of late.
