Washington Post: Madigan Declines Senate, Gov Bids

llinois Attorney General Lisa Madigan (D) will run for re-election to her current post in 2010, according to a Democratic source aware of the decision, ending months of speculation about whether she might make the leap to a Senate or gubernatorial bid.

Madigan is expected to make her decision public later today.

She had been heavily courted by the White House and the Democratic Senatorial Campaign Committee to run for the seat currently held by Sen. Roland Burris (D) and, after initially expressing no interest in the Senate, did consider a candidacy.

Madigan had long expressed an interest in serving as governor but the ouster of Gov. Rod Blagojevich (D) and ascension of Lt. Gov. Pat Quinn (D) to the top job complicated her path.
