Independent Connecticut Sen. Joe Lieberman will not run for re-election in 2012, sources have confirmed to the National Journal, a move that will likely bring an end to an often-controversial 24 years in office.
The 68-year-old lawmaker, now in his fourth term, will formally announce his decision Wednesday at 12:30 p.m. in Stamford, Conn.
The senator's retirement is likely an acknowledgment that his quixotic political journey -- which earned him the admiration and the scorn of both political parties -- has finally left him without a base and, consequently, facing long odds against a potentially strong bipartisan field.
"It'd be the heaviest lift he's ever done -- including his vice presidential run," said Jennifer Duffy, senior editor of the Cook Political Report.
One of Lieberman's favorite songs, according to a longtime associate who didn't want to be quoted before the senator's retirement was official, is Frank Sinatra's "My Way." It could have been his personal anthem.
He was a loud voice of support for former Pres. George W. Bush's war on terrorism and his invasion of Iraq. But he tried to woo Republicans to support Democratic legislation on issues like climate change and immigration reform.
