Lisa Madigan , the Democratic Illinois Attorney General who had been weighing 2010 campaigns for governor or U.S. senator, is set to announce later today that she will instead seek re-election to her current post.

Madigan’s decision was reported Wednesday morning by The Washington Post . The Chicago Sun-Times’ Lynn Sweet reported that Madigan will announce her political plans at a Chicago hotel at 3 p.m. eastern time.  

Madigan would have been a strong candidate for either governor or senator. A daughter of longtime Illinois House Speaker Michael J. Madigan, Lisa Madigan was elected state Attorney General in 2002 and overwhelmingly reelected in 2006.
