Matt Bevin

In addition to fighting off Democratic challengers, Kentucky Senator Mitch McConnell will also have to to defeat at least one fellow Republican next year.

An aide to Louisville businessman and Tea Party activist Matt Bevin distributed a news advisory Tuesday announcing stops on a statewide tour announcing his candidacy for Senate.

Bevin's entry into the race could force a shift in the McConnell campaign, which had been concentrating entirely on Democratic opponent Alison Lundergan Grimes, Kentucky's 34-year-old Secretary of State.

The move by Bevin to challenge McConnell reflects a splintering of the tea party movement in Kentucky. Many activists, including Kentucky's junior U.S. Senator, Rand Paul of Bowling Green, have already pledged their support to McConnell's 2014 re-election efforts.
