A Louisville businessman is apparently set to announce a primary challenge against Senate Minority Leader Mitch McConnell (R-Ky.).

According to a release, Matt Bevin will announce his 2014 intentions Wednesday and will embark on a three-day tour with eight campaign stops.

Bevin is widely expected to run, and the campaign-style tour would seem to confirm that fact. He has also been meeting with conservative leaders and has reportedly booked an ad buy on Kentucky television.

The official announcement is set for Wednesday at 10 a.m. Eastern time at the state capitol in Frankfort.

"On Wednesday, Matt Bevin will make an announcement about his political future," said Sarah Durand, a spokesman for Bevin. "One thing is increasingly clear: Kentucky is ready for a change from Mitch McConnell’s big government, big spending record of voting for bailouts, debt ceiling increases, and deficit spending. This is why McConnell’s approval rating is so low, why Republicans are at risk of losing the seat, and why McConnell has lost the support of so many conservatives in the Bluegrass."

Relatively little is known about Bevin, a political newcomer. But he is thought to have significant wealth to use against McConnell in the primary.

McConnell's campaign has dismissed Bevin as a "traveling con man" who is only helping Democrats.

"While it is sad to see someone who claims to be a Republican doing Barack Obama’s bidding, his campaign is nothing more than a nuisance," McConnell's campaign said last week. "Mitch McConnell will never waiver in his fight for our Kentucky values."

McConnell this month also got his first serious Democratic opponent, Kentucky Secretary of State Alison Lundergan Grimes.
