DENVER (AP) – Aurora businessman Ryan Frazier has filed an appeal with Colorado’s Supreme Court to get him into the state GOP’s U.S. Senate primary.

Frazier hasn’t collected enough voter signatures in one congressional district to qualify for the June 28 primary.

He says in the appeal filed late Monday that more signatures should be counted.

Frazier also argues that a requirement that collectors of voter signatures be registered voters themselves is unconstitutional. The status of one collector who worked on Frazier’s petition drive is a factor in his appeal.

A Denver judge ordered that Frazier’s name be placed on the ballot while Frazier appeals. Votes for Frazier won’t count if the appeal fails.

Four other Republicans hope to take on Democratic U.S. Sen. Michael Bennet in November.
