Democrat Brad Schneider is the incumbent, having served one term in Congress, campaigning alongside Vice President Joe Biden, but he realizes the 10th District is quite Independent.
"I am a proud Democrat but I don't think either party has a lock on the good ideas,” he said.
Schneider’s challenger, Republican Bob Dold, replaced Sen. Mark Kirk in the 10th District and served one term in Congress when he narrowly lost two years ago.
"I was ranked the most Independent bipartisan member during my time in Congress,” he said.
This year is a rematch of the 2012 race and both candidates are spending millions on attack ads -- with outside money pouring in. They disagree on the Affordable Care Act, Medicare Cuts and a minimum wage hike.
Dold won't give an exact number of where it should be.
"We have to recognize on a federal minimum wage, Democrats and Republicans get together and try to minimize job loss,” he said.
"I think we need to raise the minimum wage to $10.10 over three years, then index it to inflation,” Schneider said.
They also differ on the decision to send ground troops to fight ISIS.
"I don't think ground troops are the answer right now,” Schneider said.
"Ground troops certainly have to be an option on the table, we don't know what tomorrow may bring, I can tell you ISIS won't want to stop just in the Middle East,” said Dold.
The race is much too close to call, much like the governor's race. The end result will likely come down to turnout.
