The Race to the Ballot Box as 1.5 Million Coloradans Vote
More than 1.5 million Coloradans have already cast their ballots in the 2026 midterm elections. Yet for anyone who hasn’t participated yet, the window remains open. Colorado allows same-day voter registration for all eligible individuals, meaning unregistered residents can still sign up and vote before polls close at 7 p.m.
The stakes extend far beyond local issues. Control of Congress during President Donald Trump’s final two years hangs in the balance. Democratic opponents are mounting stiff challenges against all four of Colorado’s sitting House Republicans, while Democrats at the state level aim to build upon their recent streak of complete governance and secure supermajorities in the Legislature.
What Is on the Ballot
Voters across the state are deciding races for U.S. senator, eight congressional representatives, governor and three other statewide executive offices. Down-ballot choices are just as extensive, featuring all 65 state House seats, 18 state Senate seats, 14 statewide ballot measures, and numerous local contests.
For voters who received a mail-in ballot but missed the window to return it through the postal service, dropping it in a secure box or taking it to a voter service and polling center is the next step. To check their registration status or locate nearby polling places and drop boxes, individuals can visit the Colorado secretary of state’s website and input their address.
Voters who never received a mail-in ballot—or those who prefer voting in person—can visit any polling center before 7 p.m. Anyone voting in person must present a valid form of identification.
Colorado Blocks Federal Monitors from Entering Polling Locations
The final hours of voting arrive amid heightened tensions over federal oversight. Growing worries that the administration might interfere with election outcomes or reject the final tally have prompted Trump and his supporters to deploy unprecedented strategies to sway the 2026 midterms across the country, which include filing preemptive legal actions against select states.
In Colorado, monitors from Trump’s Justice Department are expected outside some voting locations in Adams County. Entry to those facilities will be denied to the monitors because the department rejected conditions proposed by Colorado authorities that would have limited what they could do inside polling sites. Adams County includes the more Democratic-leaning half of the battleground 8th Congressional District, drawing sharp warnings from the Colorado’s Democratic congressional delegation.
“I don’t want Coloradans to hear that they should be scared. They should absolutely not be scared. They should go cast their ballot,” Secretary of State Jena Griswold said during a Monday press conference.
Local election administrators have pushed back against outside pressure. Colorado county clerks declared last week that they are prepared to “go to the mattresses to make sure the voices of the voters are heard,” while Griswold emphasized that state officials are “standing strong” against any threats of federal interference.
State laws protect the voting process with strict boundaries. Electioneering is prohibited within 100 feet of any drop box or voting center. State law bans the open or concealed carrying of a gun within 100 feet of a drop box, voting center, or ballot processing facility, with exceptions only for law enforcement or uniformed security guards acting within the scope of their duties. Anyone experiencing voter intimidation or harassment can file a report with local law enforcement or reach out to the Colorado attorney general’s office.
