Frankfort, KY – GOP front-runner Rand Paul says he may not support Kentucky's other senator, Mitch McConnell, for minority floor leader if he's elected to the U.S. Senate. In a sometimes testy televised debate Monday night, Paul's chief Republican opponent, Kentucky Secretary of State Trey Grayson, said he "proudly" would vote for McConnell. McConnell has endorsed Grayson in the May 18th primary.
The debate is the final face-off in what has become an increasingly acrimonious race to replace Senator Jim Bunning. Paul, a Bowling Green eye surgeon with strong backing from tea party activists, has been engaged in a bitter race Grayson. Paul is leading in the polls.
