The ad features Bevin speaking direct-to-camera, declaring “after caving yet again to President Obama on the debt ceiling, all that Mitch McConnell can do is run false attack ads.”
A narrator goes on to declare that “thirty years is enough,” and calls McConnell “too liberal” and “too long.”
McConnell has attacked Bevin in radio ads, knocking him for what the campaign sees as a "pattern of deceptions" from Bevin.
McConnell's vote to raise the debt limit drew heavy criticism from conservatives and was seen as a risky vote for him. But the senator retains a solid lead over Bevin, and is heavily favored in the primary.
In response, McConnell's campaign spokeswoman Allison Moore charged it was Bevin himself who launched a false ad.
"Matt Bevin has no credibility and lacks even the courage to tell Kentuckians the truth about himself, where he went to school and his previous support for bailouts. It's no surprise that a campaign based on deception is producing false attack ads," she said.
