BARDSTOWN, Ky. (WDRB) -- U.S. Senator Rand Paul says he will not support President Obama's eventual nominee to the Supreme Court. And one reason is coal.

With his White House run over, Sen. Rand Paul came to My Old Kentucky Dinner Train. He's focusing now on a one-track campaign -- winning re-election to his Senate seat.

Paul is holding more than two dozen town hall meetings across the state, addressing issues ranging from the local VA hospital to what Paul says is the country's biggest issue: the vacancy on the Supreme Court.

“It's going to be very hard for me to imagine voting for President Obama's nominee,” Paul told the crowd.

Later, Paul told WDRB, one reason is coal.

“We've been so devastated from the Executive Order regulations on coal that we don't think are legal. And we're concerned that he will appoint the nominee that will decide whether they are legal or not,” said Paul

Paul has turned his attention solely to his Senate race after nine months of juggling a grueling presidential run.

“It's bittersweet. Obviously, we wanted to win, and we worked hard to win. We had a lot of enthusiasm, and we think we affected the debates. But also, I like to be able to sleep in my own bed in Bowling Green more often,” he said.

Supporters we spoke to had mixed emotions about Paul ending his White House run.

“Probably saddened some people but, for Senate, I think he's done a good job, and he has my support,” said Bardstown Mayor John Royalty.

“I guess it will be next cycle. We'll see him again in 2020,” said supporter Eric Royalty.

Paul says he does not plan to endorse any of the remaining GOP candidates in advance of Kentucky's March 5 caucus, even though he could affect the outcome.

“That's precisely why I don't want to. A lot of my supporters will pick different candidates. There are three or four main candidates that will probably still on the stage by that Saturday, and I don't want them to feel like I'm telling them what to do,” said Paul.

On Saturday, Paul heads to Lexington and Central KY, then wraps up with two stops in Hardin County. 

This series of town halls does not include Louisville.

UPDATE: Following a complaint heard at the Bardstown town hall, Paul issued letters to the Secretary of the Department of Veterans Affairs (VA), the VA Office of Inspector General, and the VA Office of the Medical Inspector urging the officials to conduct a thorough investigation into the reports of mismanagement and negligence at the Cincinnati Veterans Affairs Medical Center
