DeMint endorses Paul in US Senate race in Ky.

FRANKFORT, Ky. (AP) - U.S. Sen. Jim DeMint is at odds with Minority Floor Leader Mitch McConnell on who should be the GOP nominee for U.S. Senate in Kentucky.

The South Carolina Republican endorsed political outsider Rand Paul on Wednesday, a day after McConnell threw his support behind establishment candidate Trey Grayson.

DeMint, chairman of the Senate Conservatives Fund political action committee, called Paul "a true conservative who will stand up to the Washington establishment."

Paul and Grayson are among five Republicans seeking to replace retiring U.S. Sen. Jim Bunning, the 78-year-old sports icon who opted not to seek a third term. The winner will face 1 of 5 Democratic candidates, including Lt. Gov. Daniel Mongiardo and Attorney General Jack Conway.
