A review of voter registration data for ten counties in Colorado details a pattern of voter bloat inflating registration rolls to numbers larger than the total voting age population. Using publicly available voter data and comparing it to U.S. Census records reveals the ten counties having a total registration ranging between 104 to 140 percent of the respective populations.
Counties such as Gilpin and Hinsdale have 110 percent of their populations registered to vote. Gilpin County has a total population of 5,441 with 17.4% of the population below the voting age, making the highest possible number of registered voters 4,494. Currently Gilpin County has 4909 registered voters. Hinsdale County has a total population of 830 with 20% of the population below the voting age, making the highest possible number of registered voters 664. At 110 percent registration, that means that there are 515 excess voter registrations in Gilpin county and 68 excess registrations for Hinsdale.
