Colorado Republicans appear set to replace embattled gubernatorial candidate Dan Maes.

Maes has been losing the support of prominent backers since a story broke that he embellished his record as a police officer in Liberal, Kan. Now Tea Party groups are turning on the candidate they once supported.

"Alright Dan Maes — it's time for you to go. Get out now, while the gettin' is still good,” Lesley Hollywood, director of the Northern Colorado Tea Party, wrote on her Facebook page. And Tea Party organizer Janet Rowland, a Mesa County commissioner, called Maes a "fraud," according to the Denver Post.

"He has nobody left," state GOP Chairman Dick Wadhams said.

Maes remains defiant.

"This is a culture war, a culture war between the people and the machine, and we're going to find out who controls things," Maes said. "I am not getting out of the race."

Former state Senate President John Andrews hinted Republicans are looking at former Senate candidate Jane Norton (R) to step in for Maes.

"I intend to write in a vote for Jane Norton for governor," he said on Thursday.

Norton lost to Republican Senate nominee Ken Buck in the primary. Her entry into the race could offer the Colorado GOP a more appealing option than former Congressman Tom Tancredo (R-Colo.), who's running under the American Constitution Party banner. Democrat John Hickenlooper is considered the front-runner.
