Where to Find Official Colorado Election Results

The Colorado Secretary of State is the authoritative source for all election results in the state. Their live results portal is at results.sos.state.co.us. This site goes live on election night and updates continuously as counties upload their counting batches.

Avoid relying solely on news networks or social media for official totals. Media organizations project and call races using statistical models — these are not certified vote counts. For the actual numbers that determine winners, the Secretary of State site is the only correct source.

The SOS results site covers every race on the Colorado ballot: federal offices (President, U.S. Senate, U.S. House), statewide offices (Governor, Attorney General, Secretary of State, Treasurer), state legislature seats, judicial retention votes, and all statewide ballot measures. Local races such as county commissioner and school board are also included.

How to Navigate the Colorado Results Website

When you open results.sos.state.co.us, the homepage shows a dashboard with all active contests. Here is how to find what you need step by step:

1. Select the election. Use the dropdown near the top of the page to choose the election year and type — General, Primary, or Special. The most recent active election loads by default.
2. Browse by race category. The navigation panel lists contests grouped by office type: Federal, Statewide, State Senate, State House, Judicial Retention, and Ballot Issues. Click any category to expand the list of specific races.
3. Click a specific race. Selecting a contest opens a results table showing each candidate or option, their party, vote total, and percentage. A progress indicator shows how many of the expected ballots have been counted.
4. Filter by county. Within any race page, a county selector lets you view returns for any of Colorado's 64 counties individually. This is useful for tracking a close local contest or identifying where outstanding ballots remain.
5. Check the timestamp. A Last Updated indicator at the top of the page shows when the data was last refreshed. The site auto-updates every few minutes during active counting windows on election night.

Understanding What the Numbers Mean on Election Night

Colorado results arrive in waves rather than all at once. Understanding what the figures represent helps you interpret them accurately instead of drawing premature conclusions.

Percentage of votes counted

Because Colorado is a fully vote-by-mail state, you will see a percentage of expected ballots counted rather than a percentage of precincts reporting. This figure is calculated from the total number of ballots the county expects, based on returned mail envelopes and in-person check-ins. A county showing 60% counted still has 40% of its ballots waiting to be tabulated.

Why early returns lean one direction

Colorado mail ballots returned well before election day are typically processed and counted first. These early-return voters often skew toward specific demographics that may not represent the full electorate. Ballots dropped off on election day itself — along with in-person votes — are frequently counted in later batches. As a result, a candidate who leads early may see that lead shrink or reverse as counting continues into the night and the following days.

Reading the vote totals table

Each candidate row in the results table shows three key figures: Votes (the raw count so far), Percentage (their share of all votes counted in that contest), and in some views a Margin column showing the raw vote difference between the top two candidates. The margin figure is more useful than percentage alone when tracking a close race because it tells you exactly how many votes separate the leaders.

How to Filter Colorado Results by County

Colorado's 64 counties range from tiny rural jurisdictions like Hinsdale County, which casts a few hundred total votes, to Denver County and Jefferson County with hundreds of thousands of ballots. Filtering by county lets you track where votes are still outstanding and understand how remaining ballots might affect a statewide margin.

To filter by county on the results site:

1. Open a specific race on the results page.
2. Look for a County Breakdown tab or a county filter dropdown below the statewide summary table. The exact placement varies slightly between election cycles as the site is updated.
3. Select your county from the list. The table updates to show only that county's returns for the selected race.
4. Note the ballots cast versus expected figure for the county. This tells you how many ballots remain to be counted in that jurisdiction before it is complete.

Swing counties like Arapahoe, Douglas, Jefferson, and El Paso often carry significant weight in statewide races. Watching those specific county totals can help you understand which direction the statewide margin is likely to move as outstanding ballots come in.

When Colorado Election Results Are Certified

Election night figures are unofficial. Here is the complete legal timeline for when Colorado results become certified and final:

• Election night through Day 8: Counties process all in-person ballots and mail ballots received on or before election day. Results update daily on the Secretary of State site as counting proceeds.
• Day 8 to Day 14: Late-arriving mail ballots — those postmarked by election day but received within eight days after — are added to the count. Colorado law explicitly allows this extended receipt window, so totals continue to change during this period.
• Day 14 to Day 28: Counties conduct the risk-limiting audit (RLA), a statistically valid hand-count verification of paper ballots required by Colorado law. The RLA either confirms or flags discrepancies in the electronic totals. After the audit, counties certify their final results to the Secretary of State by Day 28.
• Day 28 to Day 35: The Secretary of State reviews all county certifications and issues the official statewide certificate of election by Day 35.

Until Day 35, any vote totals you see — including those on the official site — are subject to revision. Media race calls and projected winners are the news organization's statistical assessment, not a legal certification of the outcome.

How to Get Notified When Colorado Results Update

If you want to be alerted when new batches of results are released rather than manually refreshing the site, you have several practical options.

County election email alerts

Many Colorado counties send email or text updates on election night and during the canvass period. Visit your county clerk's website and look for a notifications or news alerts signup. For example, Denver Elections offers an email subscription through denvergov.org. Search for [your county name] Colorado election results notification to locate the signup page for your specific county clerk.

Secretary of State social media

The Colorado Secretary of State's office posts updates on official social media channels when significant result batches are uploaded on election night. Following the official SOS account gives you a heads-up without requiring you to watch the website continuously.

MyVoterPage ballot tracking

The MyVoterPage portal at myvoterpage.coloradosos.gov lets you track the status of your individual mail ballot through the stages: mailed, received, signature verified, and accepted. While this tracks your own ballot rather than overall race results, it confirms your vote has been received and is being included in the count — which is its own important data point.

News app push notifications

Major news applications let you set push notifications for specific races. The Associated Press, local outlets like The Denver Post, and television stations post real-time updates as counties release new batches. These are projections and unofficial tallies rather than certified figures, but they are useful for following the night in real time.

How to Look Up Historical Colorado Election Results

The Colorado Secretary of State archives election results from past elections at sos.colorado.gov. Here is how to access the historical data:

1. Go to sos.colorado.gov and click on the Elections section in the main navigation menu.
2. Select Election Results from the submenu. This brings up a list of past elections organized by year and type.
3. Choose the election year and election type from the available options. Results go back multiple cycles.
4. Once you select a specific election, you can browse results by contest in the web interface, or download the full results as a CSV file for spreadsheet analysis.

The downloadable CSV files include precinct-level vote totals, candidate names, party affiliations, and vote counts broken down by counting method (mail, in-person, provisional). These files are tab-delimited and open directly in Microsoft Excel or Google Sheets without any special setup.

For federal race data aggregated across all states, the Federal Election Commission at fec.gov publishes certified totals for congressional and presidential races. The FEC data cross-references with Colorado's state-level certified figures and is particularly useful for comparing results across multiple states or election cycles.
