Karl Rove's PAC readies attack against Ashley Judd

Ashley Judd addresses the crowd during Tennesseans For Obama Benefit at The Cannery Ballroom on Oct. 4, 2012, in Nashville, Tenn.

Actress Ashley Judd hasn't yet declared whether or not she'll run against Senate Minority Leader Mitch McConnell, R-Ky., next year, but a conservative super PAC is already preparing its line of attack against her.

The Karl Rove-backed American Crossroads is spending $10,000 on an online advertising campaign featuring a video called "Ashley's story." The video pokes fun at the actress for being a self-identified liberal "radical" who has said she is "committed to President Obama." It also jabs at her for calling Tennessee "home," even though her potential Senate bid would be in Kentucky.

"Ashley Judd: An Obama-following radical Hollywood liberal, who's right at home in Tennessee. I mean Kentucky," the ad concludes.

Judd, a Democrat has said she's "taking a close look" at running against McConnell. After five terms, McConnell is the longest-serving senator in Kentucky's history. Now a year ahead of his next election, he's facing pressure from the right on fiscal issues, as well as pressure from the left on gun control.
