Democratic presidential candidate Hillary Clinton will be in the state again Monday to campaign ahead of Kentucky's primary election Tuesday.

She will be making stops in Bowling Green Monday morning before heading to Lexington.

In the evening, Clinton will speak at Transylvania University. She is scheduled to start speaking at 6:45 p.m. at the Clive Beck Center on North Broadway. Doors will open at 4:45 p.m. The event is free and open to the public.

Clinton is expected to continue talking about improving education, creating jobs, and raising incomes for families who have been passed by.

Clinton's fight for delegates

In order to secure the dozens of delegates in Kentucky and get closer to securing her nomination, Clinton needs to get through her opponent, Sen. Bernie Sanders, who won in West Virginia last week.

While campaigning in Kentucky over the weekend, Sanders talked about reforming the criminal justice system, giving students free college, and raising the minimum wage.

"Hillary Clinton needs to stop the momentum Sanders has," said Dr. Stephen Voss in a Kentucky Newsmakers interview with WKYT's Bill Bryant.

Kentucky is a good state for Clinton to stage her defense against Sanders, Voss said. "On the other hand, we have very little data about where this state is going to go, so Sanders could certainly see it as an opportunity to pull an upset," he said

One important issue for many Democratic voters in Kentucky is the candidates' policies on coal. Voss, who teaches political science at the University of Kentucky, said the coal issue is a puzzle.

"I can't believe anybody in coal country would think Bernie Sanders was going to adopt policies more supportive than Clinton would of the coal industry, but Hillary Clinton did make some statements that suggested hostility to coal," Voss said. "And you know how sometimes it's what you say that matters more than what you'd do."

About the Kentucky primary

In Kentucky's primary, 61 delegates up for grabs -- five of those are super-delegates.

The Tuesday primary is closed, meaning that only voters registered as members of a particular party may vote in that party's primary. Only registered Democrats can vote for their favored presidential candidate, but the primary has other races as well that are not just for Democrats.

Kentuckians can vote for U.S. senator, U.S. representative, and in some districts, state senators and representatives.

Polls open at 6 a.m. Tuesday and close at 6 p.m.
