Rep. John Yarmuth (D-Ky.), who is perhaps Ashley Judd's biggest advocate in Kentucky, thinks the actress will challenge Senate Minority Leader Mitch McConnell (R-Ky.), according to ABC News.

"I would be surprised if she doesn't run at this point," Yarmuth said, adding: "I think in her own mind ... she has made a decision to run and she's doing the right thing and not ruffling any feathers along the way."

The Democratic bench in Kentucky is pretty thin, leaving Judd as the biggest name in the mix to challenge McConnell in 2014. Yarmuth and Gov. Steve Beshear (D) have made clear that they will not run, as has former congressman Ben Chandler (D-Ky.).

Polling has shown Judd is competitive with McConnell, who doesn't have great numbers in his home state. But while she would likely be able to raise serious money for the campaign, Republicans believe her liberal leanings and residence in Tennessee make her unelectable and have already started running ads against her on those counts.
