The Chicago Elections Board received 426 objections to nominating petitions.
Among the mayoral candidates, the biggest target appears to be former White House chief of staff Rahm Emanuel. He had 31 challenges filed against him by Tuesday's deadline. Opponents say Emanuel isn't eligible because he lived in Washington, D.C., for nearly two years.
Other mayoral candidates challenged include newcomer Rob Halpin, who is the tenant renting Emanuel's North Side home; former U.S. senator Carol Moseley Braun; and State Senator James Meeks.
