ASPEN, Colo. — A county commissioner favored by conservatives is Colorado Republicans’ pick to challenge Sen. Michael F. Bennet (D-Colo.) in November.

Darryl Glenn, an Air Force veteran, defeated four other candidates in a chaotic and surprising primary race that saw the candidate favored by the National Republican Senatorial Committee (NRSC) underperform. Glenn, an underdog in the money race with no paid campaign staff, racked up endorsements from GOP figures such as Sarah Palin and Ted Cruz that helped him sail to victory.

The Associated Press declared Glenn the winner around 7:40 p.m. Mountain time as vote tallying continued. Glenn had received 37 percent to runner-up Jack Graham’s 25 percent as of 8:30 Mountain time.

In his victory speech, Glenn recognized the voter anger that has fueled the rise of candidates such as presumptive Republican presidential nominee Donald Trump.

“[People] are tired of politicians saying one thing and getting elected to office and completely forgetting about the people that they left behind. I want you to understand that we get it,” Glenn said, according to the Denver Post.

Democrats indicated they were confident in Bennet’s reelection chances and attacked Glenn as too conservative for the state.

“The Republican Senate primary trainwreck is finally over, and even Republicans are saying that the real winner of tonight’s primary is Michael Bennet,” said Rick Palacio, chair of the Colorado Democratic Party in a statement.

“Republicans just nominated a candidate who says Donald Trump is a ‘patriot,’ thinks Ted Cruz should be the next Supreme Court justice and believes the real problem with Washington is that there is too much bipartisanship between Republicans and Democrats.”
