The campaign manager for Wyoming Republican gubernatorial nominee Mark Gordon says his campaign had nothing to do with robocalls asking Democrats to vote for Gordon in Tuesday's primary election.

The calls, from a group identifying itself as "Switch Wyoming," told voters Wyoming ''risks electing pro-Trump conservative Foster Friess as governor," and urged them to register as Republicans when they vote and to cast a ballot for Mark Gordon, whom the calls referred to as a ''reasonable moderate candidate."

The calls also reminded voters they could change their party registration back after voting in the primary election. Thursday morning Gordon campaign manager Gale Geringer called KGAB radio in Cheyenne to say the Gordon campaign had nothing to do with the robocalls.

Geringer told KGAB morning host Glenn Woods the Gordon campaign was trying to find out who was behind the calls, so far without success.  Geringer said the calls were "just another attempt to deceive the voters and blame someone else."

Gordon defeated Friess by roughly 9,000 votes and will face Democrat Mary Throne in the general election in November. You can hear a recording of the calls here.
