Republicans in the U.S. Senate are just as anxious to know the outcome of their races as they are for the White House. A Senate takeover is highly important to conservatives who want to repeal the federal health care law.
Kentucky Senator Rand Paul says it's tough to predict tonight's results.
"We've got three or four that we're trying to hang on to and we've got three or four more that we could win," says Paul. I think it's truly an election where you could go to bed tonight and wake up and still not know, and in the end you could be surprised."
Senator Paul joined in an election day tradition in his hometown of Bowling Green. He served up beans and cornbread to the public as a fundraiser for the local Lions Club. He told WKU Public Radio that many of the toss-up states for president are toss-ups for the Senate, as well. Democrats are leading in two of the most high-profile Senate races. Comments about rape and abortion by Indiana Republican Richard Mourdock and Missouri Republican Todd Akin have erased their leads, but Senator Paul maintains the election is less about social issues.
"I think the election is going to be based more on economic issues. I think 23 million people out of work is really what concerns most people," added Paul.
To gain majority control of the Senate, Republicans need to pick up three seats with a Romney win or four seats with an Obama victory. Republicans already control the U.S. House and most political analysts believe the GOP will maintain control of that chamber.
