(CNN) – Sen. Joe Lieberman, the Democrat-turned-independent from Connecticut, will announce Wednesday whether he will run for reelection in 2012.
Lieberman, who still caucuses with the Democrats, lost his Democratic primary bid in 2006 before running successfully as an independent. He has served in the Senate since 1989.
News of Lieberman's announcement comes the same day a prominent Connecticut Democratic politician, former Connecticut Secretary of State Susan Bysiewicz, announced her intentions to challenge Lieberman for the seat.
Should Lieberman decide to run, it will no doubt be a tough fight. A Quinnipiac University poll last summer showed him with a 40 percent approval rating among his constituents.
