Colorado voters head to the polls Tuesday to choose their U.S. senator for the next six years, with incumbent Democrat John Hickenlooper seeking a second term against Republican state Sen. Mark Baisley.
Hickenlooper, a former two-term governor and two-term Denver mayor, first won the seat in 2020 by unseating Republican Cory Gardner. He cruised to renomination in July, though his primary battle was tighter than expected. He defeated progressive state Sen. Julie Gonzales by less than 6 points, a sign of lingering intraparty tensions.
Baisley, a state senator from the Denver suburbs, was the only Republican to qualify for the primary ballot. Several other GOP hopefuls failed to gather enough petition signatures or secure support from party legislators, leaving Baisley as the consensus nominee.
The race is unfolding against a backdrop of national uncertainty. Recent polling shows Democrats' generic ballot advantage narrowing, and analysts are watching several Senate races that could flip control of the chamber. Colorado, a state that has trended Democratic in recent cycles, is not typically considered a top pickup opportunity for Republicans this year.
However, Baisley has sought to tie Hickenlooper to the Biden administration's policies on inflation, energy, and immigration. Hickenlooper has emphasized his record on job creation, infrastructure, and bipartisan deals, including the CHIPS Act.
Election officials are bracing for a busy day, with AI firms setting up war rooms to counter misinformation. Voters are reminded that they can skip races on the ballot if they choose, a practice known as undervoting.
Polls close at 9 p.m. EST, and results are expected to trickle in throughout the evening. For a detailed timeline of when to expect results, see our hour-by-hour guide.
Legal challenges are possible if the race is close, as some observers anticipate post-election legal battles in key states. Colorado's election system is generally considered secure, but officials are on alert.
In addition to the Senate race, Colorado voters are deciding several House contests and local ballot measures, including a preschool funding case that could test religious exemptions in public funding.
