A gay foreign policy expert who worked on international LGBT rights and served as U.S. ambassador to the Organization for Security & Cooperation in Europe has dropped his short-lived bid for a congressional seat in Colorado.

Daniel Baer, who had sought the Democratic nomination to run in Colorado’s 7th congressional district, announced in a statement Thursday he’d suspend his campaign in the aftermath of incumbent Rep. Ed Perlmutter (D-Colo.) deciding to run for re-election.

“When Ed Perlmutter decided to re-enter the race, I took time to reflect on how to move forward,” Baer said. “Running against Ed wasn’t the race I had planned; but while the race had changed, my reasons for running had not. In the end I concluded that while there would be purpose in continuing my campaign, it was less clear that there was wisdom in doing so.”

Baer had declared his candidacy in August for the congressional seat after Perlmutter, a six-term member of Congress, announced he’d retire Congress. Initially, Perlmutter had sought to become governor of Colorado, but dropped that campaign. (Rep. Jared Polis, a gay lawmaker, is still in the Colorado gubernatorial race). Weeks later in August, Perlmutter announced he’d, in fact, seek re-election to Congress.

“Ed works hard to stay connected to folks in our community and he clearly loves being our representative,” Baer said. “I’ll work hard to get Ed re-elected. I’ll send him a check, sign up to knock on doors, and urge my friends to vote for him. I hope everyone else will too.”

Under the Obama administration, Baer served not only as U.S. envoy to OSCE, but deputy assistant secretary of state for the Bureau of Democracy, Human Rights & Labor, where his portfolio included LGBT international human rights issues. After his appointment as U.S. ambassador, Special Envoy for the Human Rights of LGBTI Persons Randy Berry took over the LGBT portfolio at the State Department.

Baer was one of a record number of openly LGBT congressional candidates seeking election ahead of the 2018 midterm election. Other LGBT candidates of note are Maryland State Sen. Rich Madeleno, who seeking to become governor of Maryland; Sen. Tammy Baldwin (D-Wis.), who’s seeking re-election in Wisconsin; and Rep. Kyrsten Sinema (D-Ariz.), who’s running for U.S. Senate in Arizona.
