The volunteers will wear bright yellow shirts identifying them as nonpartisan poll monitors. Their training includes how to recognize possible immigration enforcement activity and how to de-escalate tense situations. Volunteer attorneys will also operate an election-protection hotline during the election’s final two days, and the Interfaith Alliance of Colorado plans to send faith leaders to help calm tensions.

“People are on high alert,” said Jefferson County Clerk Amanda Gonzalez, a Democrat running for Colorado secretary of state. She said voters have encountered confusion about what to expect, but emphasized that the election process is not changing.

Concerns have been sharpened by at least one confrontation this election cycle. On Oct. 17 in Salida, people possibly affiliated with the Proud Boys shouted insults at protesters who were dropping off ballots during a No Kings demonstration, according to a report cited by election advocates.

The U.S. Justice Department plans to send federal election monitors to Adams County, which is part of the battleground 8th Congressional District. Colorado officials have asked the department for details about the monitors and their planned locations before authorizing access.

Common Cause Colorado Executive Director Aly Belknap said fear could discourage eligible voters from taking part. But Secretary of State Jena Griswold said Colorado’s elections remain secure and are operating as usual.

Colorado has strengthened election protections in recent years, including banning firearms within 100 feet of polling places, making it a felony to compromise voting equipment and providing millions of dollars to counties for security upgrades.

Gonzalez urged voters to cast ballots early rather than let uncertainty keep them away. “Show up; show up early. Your voice is needed,” she said.
