LOUISVILLE, Ky. (WDRB) -- Kentucky Republicans are about to have their say in the contentious race for the White House.

The state GOP is preparing to hold its first-ever presidential caucus on Saturday.

Many questions about the caucus still linger, even as final preparations are underway.

The phone is ringing constantly at Jefferson Co. GOP headquarters. The party faithful have questions -- lots of questions -- about Saturday's first-ever presidential caucus.

"They're concerned about which location they go to. We're having to answer those phone calls, and help people figure out exactly where they're going to go," said Jefferson Co. Republican Party Chairman Jim Stansbury.

There will be nine caucus locations in Jefferson County and two in Hardin. Other nearby counties will have just one. All will be manned by volunteers.

The caucus was originally intended to allow Sen. Rand Paul to run for both The White House and the Senate. Paul dropped out of the presidential race, but the caucus goes on.

"New scares people. It scares me. But you got to be open for the new things," said Bob Hueglin, a longtime party activist in southwestern Jefferson County.

He plans to volunteer at the Greenwood Elementary caucus site.

Hueglin is cautiously optimistic about the party's switch from a May primary to a March caucus.

"It will help with the party's growth with these caucuses. And most importantly, I believe it will put Kentucky on the map," he said.

Indeed, the caucus has led to personal appearances in Kentucky by both Donald Trump and Ben Carson. All the campaigns have been working to get out their vote.

"There's not a budget, so this is all very much grassroots. It's from volunteers and individuals posting on social media," said former Congresswoman Anne Northup, who serves as Kentucky chairperson for Marco Rubio.

Back at GOP headquarters, the questions about the caucus will not be fully answered until after the polls close.

"The big measure for me tomorrow is, what kind of turnout did we get? So, until I see that, I'm kind of holding my breath here," said Stansbury.

The caucus is from 10a.m. to 4 p.m. It's for Republicans only, and it's to vote for president only.
