Candidate accuses Quinn of dirty politics

November 12, 2009 Walls is the only African American running for governor. He says Quinn is trying to knock him off the ballot to improve his own chances of getting most of the black vote in the primary election.

"it's racially based challenge of petitions of a candidate who's qualified to be on the ballot for a nefarious purpose," said Walls.

A Quinn spokesman says Walls has experience on both sides of the petition challenge process. The spokesman says Walls once failed to get on the ballot for city clerk because he didn't have enough legitimate signatures and another time unsuccessfully challenged Chicago Mayor Richard Daley's nominating petitions.
