Some voters in Weld, Adams, Arapahoe and Douglas counties received ballots containing Colorado Ballot Issue 7A, a proposed tax increase for the Front Range Passenger Rail District, even though boundary changes may have made those voters ineligible to weigh in on the measure. The question would raise taxes to fund the district and its proposed Colorado Connector passenger rail service. The confusion surfaced after the district’s boundaries were changed this spring, before Gov. Jared Polis signed legislation establishing the revised boundaries. Weld County Clerk and Recorder Carly Koppes said the town of Erie was included in the district’s original boundaries, but not in the updated version. She said the revised boundaries do not appear to have been properly communicated to all county clerks and recorders. “There are potentially voters that got the question that should have not received that question,” Koppes said, adding that the situation raises a legal question. The district’s general manager acknowledged that county election offices should have been walked through the boundary changes. The district said it was not legally required to do so, but that doing so could have prevented confusion. With ballots already printed and distributed, election officials will continue processing them as they are returned, Koppes said. If officials are directed to invalidate votes on 7A cast by ineligible voters, they can isolate that question without affecting the rest of a ballot. Ballot timing marks and barcodes help election workers identify different ballot styles, including which ones contain the disputed question. Koppes said the safeguards allow officials to count voters’ other selections even if a 7A vote must be set aside. The dispute puts a spotlight on the coordination required when district boundaries change close to an election. Election officials say the ballot issue can be handled without discarding voters’ choices in other races or measures.
