Colorado is a caucus state in that delegates to the state convention are elected from caucuses and county assemblies. It is common to petition onto the primary ballot if another candidate packs the caucuses.
Tina Peters is very controversial for a statewide candidate because last I heard she is under indictment. Mike O'Donnell had essentially the same platform as Tina but no indictment, so they split that vote.
Pam Anderson was the Republican clerk in Jefferson County, a large suburban county, so a known quantity in the Denver metro. Her primary win is not considered a major upset.
Say all you want -ole Pam had Zuckerturd in her camp + BS voting machines. This = a winner. Conservatives be prepared for the letdown this fall. Same ole-same ole. The cockroaches will be alive for fall & a take down in 2024. (No consequences for their cheating)
