Jon Keyser, one of the leading candidates for the Republican nomination for U.S. Senate in Colorado, is on the August primary ballot. However, his spot is being challenged by activists who say they have identified ten voters whose signatures are on the petition, but who say they didn’t sign it. See this story.

The state originally said Keyser had failed to collect enough signatures to appear on the primary ballot. But it was later ruled that Keyser had enough valid signatures to qualify for the Republican primary June 28.
