Kirk vs. Duckworth for Illinois U.S. Senate seat

SHILOH, IL (KPLR)- Republicans and Democrats are fighting to the end for control of the U.S. Senate. In Illinois, it's a contentious race between incumbent Republican Senator Mark Kirk and his challenger Representative Tammy Duckworth. Democrats hope to recapture a seat in Illinois with Duckworth in their effort to take back the Senate while Republicans try to hold on to Kirk and control of GOP. A Clinton victory would mean Democrats need to take four seats currently held by the GOP.

If Trump wins, they'd need five.

The Illinois Senate race has been fiercely competitive. But with less than two weeks before Election Day, the Kirk campaign suffered a major blow when Kirk commented at a televised debate that Duckworth's parents came to the U.S. to "serve George Washington." Kirk has since apologized. As for Duckworth, she's been dealing with a workplace retaliation lawsuit for much of the year.

In Shiloh, Illinois voters filed in steadily to cast their votes at the Cornerstone Christian Church since the polls opened at 6 am. Included in that first rush was famous undecided voter Ken Bone sand the red sweater, who became an Internet sensation following the question he asked at the second presidential debate.

Bone wouldn't reveal his choice for president but said he made his decision shortly after the third presidential debate. Where was the noticeably absent red sweater? He said he left it at home in hopes of keeping the focus at the polls off of him and more on the election.

Polls in close at 7 p.m. tonight.

According to election officials in Illinois, if a voter is in line by the time the polls close, they will still be allowed to vote.
