Libertarian gubernatorial candidate Nicholas Gluba and his running mate, Jules Cutler, are challenging an Iowa state decision to remove them from the Nov. 3 ballot.

A panel comprised of Attorney General Brenna Bird, Iowa Secretary of State Paul Pate, and Secretary of Agriculture Mike Naig, who are all Republicans, ruled last week that the running mates failed to submit the required affidavit of candidacy by the required June 2 deadline to appear on the ballot.
