DENVER — Republican candidate for U.S. Senate in Colorado Jon Keyser fell 86 signatures short of making the Senate primary ballot, the Secretary of State’s Office said Monday. Some observers see Keyser as the best chance to beat incumbent Sen. Michael Bennet in the fall.

Keyser, a former state representative, needed to get 1,500 valid signatures from Republican voters in each of Colorado’s seven congressional districts for a total of 10,500.

He was short 86 signatures in Congressional District 3. The district covers the western third of the state and an area of southern Colorado that extends to the eastern Plains.

The Secretary of State’s Office said Keyser submitted 16,067 signatures. After a line-by-line review, 11,436 were determined to be valid.

Keyser’s campaign can protest the decision within five days.

“We are confident that we secured the necessary number of signatures to appear on the ballot and we will be pursuing legal action to ensure thousands of Coloradans are not disenfranchised,” said Matt Connelly, communications director for the Keyser campaign.

Keyser is attempting to get on the June 28 primary ballot, which is a mail-in ballot. He is one of four Republicans who submitted signatures to get on the ballot.

Former Colorado State athletic director Jack Graham made the ballot last week. Signatures are still being reviewed for other GOP Senate hopefuls Robert Blaha and Ryan Frazier. Results for them are expected this week.

El Paso County Commissioner Darryl Glenn is on the GOP ballot. Bennet is on the Democratic primary ballot and is running unopposed.
