[TPM SLIDESHOW: Meet Your New Governors]
Quinn was first elected lieutenant governor in 2002 and re-elected on the Democratic ticket in 2006. He succeeded to the governorship in 2009 following the impeachment and removal of Dem Gov. Rod Blagojevich, as a result of a scandal involving allegations that Blagojevich conspired to sell the appointment to President Obama's former Senate seat.
As a result of the state's ethics scandals and the rough economy, Quinn suffered from poor poll ratings through his whole term so far. He barely survived a primary challenge earlier this year from state Comptroller Dan Hynes, and trailed in nearly all the general election polls.
As such, his narrow win stands out as a rare come-from-behind win for Democrats this year -- even if it was something as basic as a win by an incumbent in a Dem-leaning state.
