The Washington Post is reporting that Joe Lieberman (I-CT) will not seek reelection to the Senate in 2012:
Lieberman's office did not offer any comment on his plans, saying only that he would make an announcement tomorrow in Stamford, Conn. "The Senator's remarks tomorrow will stand on their own," said a Lieberman spokeswoman.*Lieberman is an independent, but caucuses with the Democrats.
Lieberman will be the second* Democratic senator to make public his plans to leave the chamber in the past 24 hours. On Tuesday morning, North Dakota Sen. Kent Conrad said he would not seek a fifth term in 2012.
