Michele Piszczor gave a series of short speeches in front of the county building at 69 W. Washington.
She says she's Madigan's only real opponent in the house race.
"No one has really challenged and he doesn't think he needs to earn the peoples' vote and no one's even given him a reason to think otherwise," Piszczor said.
A spokesman for Madigan says there's no evidence that voters have any idea what Piszczor is about.
They claim her campaign is funded by right wing Republicans.
