Primary results
On June 30, 2020, Lauren Boebert defeated Scott Tipton by a 54.6% to 45.4% margin to win the nomination. During her campaign, Boebert criticized Alexandria Ocasio-Cortez and other members of "The Squad", positioning herself as a conservative alternative to Ocasio-Cortez. Dick Wadhams, a Republican political consultant from Denver, says that Tipton had several hundred thousand dollars in the bank for his primary against Boebert, but he chose not to use it for TV/radio ads, mailings, or social media, ceding the debate to Boebert, who inspired a much higher Republican turnout than in 2018.
