Colorado voters are casting ballots in droves ahead of the 2020 election, pushing early vote totals to record levels in the first days.

As of Oct. 27 — 7 days before the Nov. 3 election — 1,915,926 people cast ballots, or 45.5% of registered voters, a Colorado Sun analysis shows.

This is the second presidential election in Colorado with mail ballots — and an unusual one. The coronavirus pandemic and attention on mail ballots is driving numbers to all-time highs and scrambling traditional turnout patterns.

So far, registered Democrats represent the largest group of early votes at 56%, followed by Republicans at 44% and unaffiliated voters not aligned with a political party at 39%.

In Colorado, mail ballots are sent to all active registered voters and began to hit the mail Oct. 9. The vast majority of the early votes cast to date are mail ballots. Only 2% came from in-person voting, according to the state. People may register to vote and cast a ballot until 7 p.m. on Election Day. 

Here’s a look at who is voting early — and how many people voted in the 11 largest counties, which account for 84% of registered voters.

About the numbers: The Colorado Sun receives early vote data directly from the Secretary of State’s Office. This data may differ from the daily reports released by the state because The Sun’s tracker is updated more frequently.

VOTER GUIDE:


Colorado counted 4.1 million voters at the start of October, according to the latest figures available. That’s a 10% increase since the 2016 election, up 386,687 voters.

The nearly 2.8 million Colorado voters who cast ballots in 2016 ranked the state fourth in the nation in turnout at 71.9% of the eligible voting population, according to the U.S. Elections Project.

The 2020 turnout is exceeding the previous presidential election, but it’s important to note that  the initial numbers were artificially inflated because voters began to receive their ballots four days earlier.


The partisan breakdown of the early vote in Colorado
