Frankfort, Kentucky - Republican Matt Bevin is airing radio ads depicting Senator Mitch McConnell as an out-of-touch Washington insider.
Bevin characterizes the Senate race as a fight for "the heart and soul" of the political process.
He is trying to unseat the five-term Republican Senate leader in the May GOP Primary in Kentucky.
McConnell campaign spokeswoman Allison Moore says Bevin came out with the "lame attacks" just a day after he denounced negative campaigning.
The May primary is set for May 20th.
