CHICAGO (AP) -- The Republican primary for Illinois governor is approaching after a campaign that featured unprecedented involvement by labor unions, allegations of sexual harassment and millions in spending by one candidate.
Wealthy businessman and front-runner Bruce Rauner says he wants to "shake up" Springfield and its "career politicians."
To win the GOP nomination on Tuesday, he must top three longtime lawmakers -- state Sens. Bill Brady and Kirk Dillard and Treasurer Dan Rutherford. They say they have the experience and expertise needed to run the state.
Republican leaders consider the election critical to winning the governor's mansion for the first time in more than a decade and regaining some control in a state government dominated by Democrats.
They see Democratic Gov. Pat Quinn as vulnerable because of Illinois' financial troubles.
