Ed Brewer

Former Douglas County Republican Party Chair Mark Scheffel was the only one of four candidates to make the ballot from Friday's SD-4 GOP assembly.

Scheffel, a Parker attorney, won 65 percent of the assembly delegate votes.

Precinct 131 Committeeman Ed Brewer of Castle Rock won 25 percent of the vote, but since he did not submit petitions to the Colorado Secretary of State's office by the May 29 deadline, he's out of the race.

Castle Rock Mayor Randy Reed and computer consultant Mark Vanderbilt of Castle Rock are out of the race after receiving 7 percent and 2 percent of the votes, respectively.

Meanwhile, retired Air Force Colonel Bob Denny of Glen Eagle has submitted petitions to the Colorado Secretary of State's office. Two other SD-4 candidates who had planned to petition, Precinct 58 Committeeman Roger Partridge of Castle Rock, and SD-4 GOP Chair John Peterson of Castle Rock, did not turn in petitions by the May 29 deadline.

With state Sen. Tom Wiens (R-Castle Rock) announcing last week that he wouldn't seek re-election this fall, a lot of would-be successors have popped out of the woodwork.

"I think there's about 45,000 registered Republicans in the (4th Senate) district, and I think 40,000 are thinking about running for the seat," said state Sen. Ted Harvey (R-Highlands Ranch).

Five Republicans have confirmed to PolitickerCO that they will run for the seat: Precinct 131 Committeeman Ed Brewer of Castle Rock, Precinct 58 Committeeman Roger Partridge of Castle Rock, SD-4 GOP Chair John Peterson of Castle Rock, former Douglas County Republican Party Chair Mark Scheffel of Parker, and computer consultant Mark Vanderbilt of Castle Rock.

Other talked-about potential SD-4 Republican candidates, including state Rep. Amy Stephens (R-Monument), GOP activist Bill Henry, District 2 Captain David Gill, U.S. Rep. Tom Tancredo (R-Littleton) outreach coordinator Charcie Russell, and Douglas County Commissioner Steve Boand, have all said they will not seek the position.
