The Colorado primary is June 26. El Paso County election officials decided not to print up any primary ballots for the Democratic Party or the American Constitution Party, because those two parties have no primary contests within the boundaries of the county. But the Colorado Secretary of State believes each county must print up primary ballots for all three parties that are entitled to nominate by primary. See this story. The Secretary of State apparently will sue the county to get a judicial decision on this issue.
El Paso County is a populous county that contains Colorado Springs.
