From 2008 to 2014, he served as the Small Business Administration's Colorado director. He previously served as mayor of Parker, Colorado, and ran for Governor in 2018 and 2022. He was the Republican nominee for the 2024 special election in Colorado's 4th congressional district to replace Ken Buck, who resigned in March 2024. He did not run in the general election for a full term. He was elected to the United States House of Representatives in June 2024. He is currently an independent candidate for governor of Colorado in the 2026 election.

Early life and education A third-generation Mexican American, Lopez grew up in Irving, Texas, with parents and grandparents who were farm workers. Lopez joined the United States Air Force upon graduating from high school and used the military benefits to pay for an associate's degree in business administration from New Mexico State University Alamogordo. Lopez and his wife, Lisa, moved from Texas to Colorado in 1988.

Career Lopez served in the United States Air Force 1983 to 1987 as a weapon specialist at Holloman Air Force Base. In that role, he prepared airplanes for flight and left active service after sustaining significant hearing loss from airfield work.

Mayor of Parker Lopez was elected Mayor of Parker at 27 years old in 1992 as a Democrat, but switched parties in 1994. As Mayor, Lopez was for managed development and growth. He lost the primary to Heidi Ganahl by seven points.

U.S. House of Representatives 2024 special election

Lopez was selected as the Republican nominee for the 2024 special election in Colorado's 4th congressional district caused by incumbent Ken Buck's resignation. He won the nomination in the sixth round of voting by a nomination committee, beating Logan County Commissioner Jerry Sonnenberg by a vote of 51 to 46. Much of Lopez's pitch to the committee voters was as a placeholder candidate. His selection as the nominee over Sonnenberg, a candidate running in the regular primary in the 4th district, was considered a boon to Lauren Boebert, who won that regular primary (after moving from the 3rd district); she was running for the full term but not in the special election, as she already enjoyed incumbent status.

Tenure Lopez shaking hands with Speaker Mike Johnson after being sworn inFollowing his victory, Lopez penned an op-ed in The Denver Post, pledging to not "buy, sell, or trade individual stocks" while in Congress, and to not miss any votes. He was sworn in on July 8, 2024.
