Elected officials

2020-2021 county clerk election issues

In August 2021, it was reported that the Mesa County Clerk, Tina Peters, let someone who should not have been there during an important update to the county's voting software in May 2021. This caused problems with the voting tools for the fall 2021 election.

There had been problems with Peters before. In February 2020, it was found that her office did not count 574 ballots from a dropbox outside her office in the November 2019 election. These ballots were not counted for three months and were only found when her office checked the dropbox for ballots from the 2020 presidential primary. This led to an attempt to remove Peters from her job, but it was not successful.

In March 2022, Peters was charged with several serious crimes related to the security issue in May 2021. Her deputy, Belinda Knisley, was also charged. At the time, Peters was running for a job that would oversee elections in Colorado. In May 2022, a judge stopped Peters and Knisley from managing the November 2022 elections in Mesa County.

On August 12, 2024, Peters was found guilty of several charges. She was sentenced to 9 years in prison, with the first 6 months to be served locally and the rest in a state prison. She was also fined $3,000. As of October 2025, Peters is serving her sentence in a prison in Pueblo.
