The last Democratic presidential candidate to carry the county was Franklin D. Roosevelt in 1940, and in the last seven Presidential elections no Democratic candidate has managed to receive more than 15.1 percent. The last Democrat to pass so much as thirty percent was Lyndon Johnson during his 1964 landslide win over Barry Goldwater, and even then Goldwater won the county by double digits and it was his second-best county in the Treasure State behind Powder River.
