The 1966 United States Senate election in Arkansas took place on November 8, 1966. Incumbent U.S. Senator John L. McClellan was re-elected to a fifth term in office.
Because the Republican Party (or any other party) did not field a candidate in the general election, McClellan's primary victory was tantamount to election.
For the first time since 1954, Senator John McClellan faced a challenger for the Democratic nomination, Foster Johnson, a 51-year-old book salesman and political neophyte. McClellan did not stage a formal campaign for re-election and ignored his opponent.[1] Johnson did win the support of organized labor in the state but attracted little attention to his campaign otherwise.[1]
