In the newest political development for the 2010 Illinois Senate race, state Attorney General Lisa Madigan will reportedly announce that she is not running for Senate -- nor is she running for Governor -- but will simply run for re-election.

The seat, of course, is currently held by the very controversial Democrat Roland Burris, who was appointed by the later-impeached Gov. Rod Blagojevich, and was formerly held by Barack Obama. State Treasurer Alexi Giannoulias is currently running for the Democratic nomination, and has raised a decent amount of money, while Burris has not made his plans clear.

There had been much speculation about whether Madigan would run for Senate, or perhaps challenge the new Gov. Pat Quinn in the Democratic primary. Instead, she's sticking with her current job.

Polls had consistently shown that Madigan would have won Democratic primaries for either of those two offices. Now that she seems to be out, Giannoulias appears to be the frontrunner for Senate, and Quinn can probably breathe a sigh of relief.
