On April 24, a Denver District Court kept Democratic nominee Trisha Calvarese on the ballot in the special election for U.S. House, District 4, set for June 25. Glasser v Griswold, 2024=cv=31103. The challenger had argued that Calvarese should not be on the ballot because she has not been a registered Democrat in Colorado during the twelve months before the party nominated her. Calvarese was a registered voter in Virginia during part of that period, and was a Virginia resident. Virginia doesn’t have registration by party so while she was living there she couldn’t possibly be a registered Democrat.
The state court ruled that she should remain on the ballot. Here is the 19-page decision.
