A third candidate, independent Vic Alton, rounds out the candidate field for Moffat County Sheriff.
As an independent, Alton successfully petitioned his way onto the ballot.
Because of his independent status, he will not be listed on the ballot for Tuesday's Republican primary. He automatically advances to the November general election.
Alton, a deputy with the sheriff's office, has been in law enforcement for 35 years. He has said his campaign platform is simple: law enforcement.
He lists protecting county residents and their property as primary concerns, as well as fighting the county's escalating drug problem.
Alton, who has been with the Moffat County Sheriff's Office since 2000, is a past police chief in Washington state and undersheriff in Routt County. He also worked for the International Police Task Force in Bosnia-Herzgovina in 1998, training police officers in the war-torn country.
Alton has not announced who he would name undersheriff should he win the general election. He said he prefers to run his campaign "on my own merit."
