LOUISVILLE, Ky. (WDRB) -- Stand with Rand or Go with Gray: that's the choice voters face, Tuesday, in Kentucky's only statewide race.

The U.S. Senate candidates spent the eve of Election Day barnstorming the state trying to get out the vote.

Polls show Senator Rand Paul with a healthy lead in this race -- so if Democrat Jim Gray is going to pull the upset, he'll need lots of help from Louisville.

Gray is counting on big labor to turn out his vote. He campaigned at a union hall this Election Eve, and brought the big guns in the form of Louisville Mayor Greg Fischer, Congressman John Yarmuth and former Gov. Steve Beshear.

That said, Gray knows Kentucky has not had a Democratic Senator since Wendell Ford left office in 1999. That's why he's downplaying party politics and zeroing in on Rand Paul's record, using what has become his favorite expression.

"His wild-ass theories, his ideas, they are not mainstream. They are not going to build the first bridge or highway or factory," Gray told reporters.

Yarmuth says Gray not only has to win Louisville, but win by a big margin to make up for the state's rural areas, which appear to favor Paul.

"It's absolutely critical. A Democrat can't win statewide unless he or she runs up a huge margin in Louisville metro. And I think Jim is poised to do that," said Yarmuth.

A crowd of supporters welcomed Senator Paul as he touched down for a rally at Bowman Field. During his speech, Paul never mentioned Jim Gray.

"We had a little debate, which still kind of cracks me up, with my opponent, I can't remember his name," Paul joked as he addressed his followers.

Paul, instead, focused his attacks on Hillary Clinton.

"Hillary Clinton should never get within 10 miles of the White House," Paul said to cheers from the crowd.

And Paul's effort to fire up his base, apparently, did not include answering reporters' questions.

"I'm not going to do interviews. We're just sort of talking to the crowd," Paul said when approached by WDRB.

Paul's supporters believe he'll hold his own in Louisville because of the presidential election.

"I think he's bolstered by the Trump race. People will show up," said Rep. Phil Moffett (R-Louisville.)

Both Gray and Paul are making eight stops across the state, with both ending in their hometowns, Gray in Lexington and Paul in Bowling Green.
