In his bid to be Colorado’s Republican candidate for governor in 2006, second-term Congressman Bob Beauprez is garnering some early key endorsements, just as the Marc Holtzman campaign has been picking up momentum.

Former Congressman Bob Schaffer, who now holds the official GOP position of Colorado’s National Committeeman, has given Beauprez a big boost with his thumbs-up, one that should resonate with the party’s hard-core conservative voters. I’m not sure that in the midst of the Referendum C/D battle that the Governor Owens endorsement is that helpful with most voters who will participate in next year’s Republican primary. Then again, how many are even paying attention at this point? Some might interpret the Governor’s move as taking Holtzman, a personal friend and former cabinet appointee of his, to task for privately chastising his support of Ref. C, “the forever tax increase.”

But surely Beauprez needs the big-name endorsements at this point to offset the pending announcement that the Holtzman campaign has the early fundraising advantage. Or will the 7th District Congressman be irrevocably branded as the “Establishment” candidate?

All the GOP “Establishment” heft is there: Add Schaffer and Owens to a list of big-name Beauprez supporters that includes State Treasurer Mike Coffman and U.S. Representatives Marilyn Musgrave and Joel Hefley.

It’s sure shaping up to be an interesting gubernatorial primary, but will they wear out the voters too early?
