Sen. John McCain, R-Ariz., volunteered to campaign for Wyoming Senator Mike Enzi, who's facing a challenge from Republican Liz Cheney, the daughter of the former vice president.
"I have grown to admire and respect Mike Enzi. I'll tell you, he's one of these solid guys," McCain, 76, said in an interview on Bloomberg Television's "Political Capital with Al Hunt." "I know nothing that Mike Enzi would do that didn't deserve re-election."
McCain said he would never tell anyone including Cheney, 46, former Vice President Dick Cheney's eldest daughter, they shouldn't run for office. But he called Enzi, 69 and seeking his fourth Senate term, "the epitome of a workhorse," with expertise in health care and tax issues that has impressed Republicans across the board.
