McConnell lamented Utah conservatives' decision at a party convention on Saturday not to renominate Bennett as the GOP's Senate candidate in the state.

"Utah — and the nation — has lost an outstanding conservative Republican senator," McConnell said on ABC News's "Top Line" webcast.

Bennett had served as a member of the Senate Republican leadership as counsel to McConnell, and was considered a top ally of the minority leader.

"It is the only state in the country where you don't have a way to get on the ballot unless you go through a convention," McConnell said, noting the unusual circumstance in which Bennett was defeated without a statewide primary vote.

"We've got a unity rally scheduled for the Saturday after the Tuesday primary," McConnell said, downplaying the reported rifts in the state over the race. "I think there's an excellent chance that Kentucky will keep this seat in Republican hands."
