Democratic challenger Brad Schneider will be watching the returns Tuesday night at the Hilton in suburban Northbrook.
Republican Robert Dold will be in suburban Lincolnshire.
The 10th District is often seen as one of the more Democratic-leaning districts in the country with a Republican as its congressman. Schneider, a Deerfield business consultant, seeks to change that. He was met by sign-waving supporters Tuesday morning as he voted in Highland Park. Schneider has spent a good bit of his campaign's time and money trying to portray his opponent as a tea party Republican.
Dold, the first-term congressman who succeed Mark Kirk, says his voting record shows he's a moderate, unafraid of breaking with his party. As Dold campaigned Tuesday, he was warmly greeted by diners at the Liberty restaurant in Libertyville, save for one woman who works the night shift and complained she couldn't get any sleep due to calls from Dold's campaign and others. Dold responded to that by saying the good news is it's over.
