Sen. John McCain said Sunday that he will “absolutely” support his colleague Sen. Mike Enzi over Liz Cheney in Wyoming’s Senate race.

“I’m pleased to see that most people who have served with Mike Enzi have expressed our strong support, because he’s a good, solid, hardworking workhorse,” McCain said on CNN’s “State of the Union.” “In the old line about showhorses and workhorses, Mike Enzi is the epitome of a workhorse in the Senate.”

Indeed, Enzi’s Senate colleagues have so far come out in strong support of the lawmaker, who faces e a Republican primary challenge from Cheney, the daughter of former Vice President Dick Cheney. In the immediate aftermath of Cheney’s announcement, Sen. John Barrasso, also a Wyoming Republican, said he would back Enzi; and Sen. Jerry Moran, who leads the National Republican Senatorial Committee, affirmed the committee’s support the incumbent.

In the first Harper poll released after Cheney’s announcement this week, 55 percent backed Enzi and 21 percent supported Cheney.
