For years, Colorado’s voter turnout has surpassed the national average, even in midterm elections, where overall voter turnout tends to be lower. June’s primary election saw the second-highest voter turnout for a primary since 2010, with 36 percent of Colorado’s active registered voters casting their ballot (the highest was 45 percent in 2020). With a hefty slate of statewide ballot questions, and at least 90 Colorado municipalities holding elections, we can anticipate a healthy voter turnout in November.

Some national trends in elections since 2020 include:

  • Overrepresentation of voters with high family incomes and bachelor’s degrees
  • Increase in “nontraditional” voting, or voting early or by mail instead on in-person on election day
  • Voters aged 45-64 made up one-third of the voting population in 2024, following a shrinking trend since the 2012 election, when this group made up nearly 40 percent of voters
  • Of registered voters who did not vote in 2024, 19.7 percent listed their reason for not voting as lack of interest, or feeling their voice would not make a difference

Here is how Colorado voter turnout shaped up in the 2024 general election:
