Possible Tea Party Candidate to Run for Senate

FRANKFORT, Ky. (AP) -- Senate Republican Leader Mitch McConnell, already facing a stiff Democratic challenge for re-election, could pick up a tea party primary opponent later this week.

Louisville businessman Matt Bevin's entry into the race would force a major shift in the McConnell campaign, which has been concentrating entirely on the chief Democratic opponent, Secretary of State Alison Lundergan Grimes.

Bevin is scheduled to announce his intentions on Wednesday at the state Capitol in Frankfort, after which an aide said he will begin a three-day statewide tour.

University of Louisville political scientist Laurie Rhodebeck said Bevin's entry into the race would cause McConnell to spend time and money on the primary when he'd much rather focus exclusively on Grimes.
