Colorado Presidential 2028 Election Turnout

The 2028 presidential election will bring out Colorado’s largest number of voters. The following chart shows voter turnout among Colorado, regional and Denver voters in the 2016 and the more recent 2020, 2022, and 2024 elections. Denver’s most recent bond election had 192,000 votes (2025), an unusually high number of voters for an off-year/off-year event. The falloff of votes in 2024 from 2020 reflects Colorado’s population slowdown and a presidential candidate less attractive for Democratic voters.

Colorado’s 2026 mid-term election for U.S. senator, governor, statewide constitutional offices can expect about 2.5 million voters.

The next presidential election will likely be very competitive within party primaries and between the parties in the general election. Highly polarized voters, especially on cultural issues, can be expected. The Denver region should see more than 1.7 million votes, the turnout in 2024.

Colorado Democratic Party Nominations Tend to Go to Money and Establishment

In the Colorado Democratic Party’s two-phase nominating system, activists often dominate its old-time caucus system but don’t win the nomination in the later voter primary. Governor Jared Polis and Senator John Hickenlooper both lost their party convention/caucus endorsements in their first elections but went on to win primaries and then general elections. That history bodes well for Senators Michael Bennet and John Hickenlooper winning their nominations and general elections in spite of party challenges.

Hickenlooper has left-wing challengers who may excite some grassroots progressive support (Julie Gonzales and Karen Breslin) but their campaigns so far have attracted little attention and less money. History suggests the Democratic party’s progressive wing can’t beat the party’s establishment candidate. Hickenlooper, as a former mayor, governor and now senator is the well funded, old guard incumbent.

Bennet vs Attorney General Phil Weiser race doesn’t have a clear moderate vs. progressive atmosphere although Weiser is the candidate closer to home. Senators are frequently burdened by the distance and poor image of Washington DC. But as winning the caucus vote shows, party activists’ support doesn’t make up for money and endorsements in the primary, Bennet advantage. Whichever one wins will likely win the general election.
