Roughly 800,000 Colorado voters have received ballots carrying a passenger-rail tax question they are not eligible to decide, after election officials in four counties used an outdated district map to build their ballots for the November election.
The measure, listed as Issue 7A, would create a 0.333 percent sales and use tax to fund the Front Range Passenger Rail District — generating an estimated $295 million a year and supporting $580 million in debt for a line connecting communities from Pueblo to Fort Collins. State lawmakers narrowed the district’s boundaries this year to 31 cities along the planned route, but the updated map never reached clerks in Adams, Arapahoe, Douglas and Weld counties through the usual channels, according to the officials involved.
The scale varies sharply by county. Adams County reported about 275,000 affected ballots, Arapahoe about 262,868, and Douglas County placed the question on all 289,000 of its ballots although only about 5,967 residents are eligible under the revised map. The rail district has apologized to the clerks for the communication failure.
The secretary of state’s office has directed counties to program their tabulators to count Issue 7A votes only from eligible voters, with extra testing and, in a few split neighborhoods, individual hand review. Officials stress that voters should not request new ballots: the one they received is valid, and only the rail question will be filtered. One opposition figure has argued the measure itself should be thrown out — a question officials say would be for the courts.
How a ballot is built, and where a map error can enter
County election offices build each ballot style by combining the races and questions for which a voter is eligible at a registered address. That work depends on geographic information system files that assign every address to its federal, state, county, city and special district boundaries. A special district that covers only part of a county, or only selected municipalities within it, creates many more ballot combinations than a countywide contest.
When a legislature changes a district boundary, the updated shape must be transmitted, imported and checked against voter registration addresses before ballots are designed and proofed. An outdated map can therefore produce a systematic error rather than a random one: every voter in an area removed from the district may receive the question, while the ballot itself, the envelope and the other contests remain entirely valid. That distinction is why officials can direct tabulators to filter one question by eligibility instead of reissuing an entire election.
What tabulator filtering and hand review involve
Modern tabulation systems count votes according to the ballot style and precinct assigned to each ballot. Programming them to count a district question only for voters inside the revised boundary requires logic and accuracy testing before counting, additional test decks, and documentation that ineligible marks on that one question are not tallied while all other contests are counted normally. Split precincts are the hardest cases because a single geographic precinct can contain voters on both sides of a district line, sometimes differing by street or by side of a street.
Voters who received the affected ballot do not need to diagnose that geography themselves. The instruction in the report is to vote and return the ballot as directed, and to contact the county clerk with questions rather than requesting a replacement that could create duplication risks. What to watch next is the formal certification process, any pre certification audits or recount procedures available under state law, and whether a court challenge targets the administration of the question or the measure itself. Those are separate issues, and election officials will need a clear public record showing which ballots carried the question, which voters were eligible, and how the filtering was tested.
