Republican Rand Paul is phasing out TV ads attacking his chief GOP primary opponent in the Kentucky Senate race.
He's opting instead to run affable spots featuring some of his more prominent supporters.
It will be a radical change in tone in a bitter fight for the nomination to run for retiring Republican Sen. Jim Bunning's seat.
Polls show Paul, a tea party favorite, with a double-digit lead over Secretary of State Trey Grayson, his top rival in a five-way primary Tuesday.
The ads he's taking off the air paint Grayson as a desperate career politician who is part of the Washington political machine.
Grayson campaign manager Nate Hodson says he's pleased Paul decided to pull the ads.
