Tuesday, June 28, 2016 is the final day to deliver you mail-in primary ballots to polling places in Colorado. It is too late to mail these ballots. But, there are many drop off locations near you. Primary ballots are distributed only to voters who are registered to vote and affiliated with a political party.
These ballots do not include a Presidential primary vote as Colorado's Democrats had a Presidential caucus and Colorado's Republicans denied its rank and file a say in the Presidential nomination process.
