Tom Tancredo, Colorado’s perennial entrant in the national Our Crazy Guy Is Crazier Than Your Crazy Guy competition, has told Scott McIsn’t and Dan “Who the Hell Am I, Anyway? Maes to drop out of the GOP gubernatorial race or he’ll jump in as a third-party candidate.

“Mexicans! Communists! Terrorists! Abortionists!” said Tancredo. Well, not yet. But it’s coming.

Tancredo says he’ll run under the banner of the Constitution Party, which could (and probably should) hold its convention in a short bus, with free rubber helmets for all attendees.

The party already has a candidate — Benjamin Goss, another household name — but he doesn’t sound all that committed. On Wednesday, he told The Denver Post that he remained in the race “at this point.” Uh huh. And Bert Grabsch remains in the Tour, too. He’s just not gonna win it.

The stage GOP is shitting itself, naturally. Dick Wadhams, chairman of the Colorado GOP, told The Post that if Tancredo carries through on his threat, he “will be responsible for the election of Denver Mayor John Hickenlooper as governor” and jeopardize other state races.

Well, then. As another great leader once said, “Bring it on.”
