Politics
With its rural German-American heritage, Campbell is an overwhelmingly Republican county. It has only once been carried by a Democratic presidential candidate, during Franklin D. Roosevelt’s landslide victory of 1932. Nonetheless, in the following election when FDR gained an even more emphatic victory by carrying forty-six of forty-eight states, his Republican opponent Alf Landon carried Campbell County by twenty-five percentage points, making the county Landon's second-strongest in the Plains States (behind Brown County in his home state). Since 1940, no Democrat has so much as equalled Roosevelt's 1936 share of the vote, and even before 1932, only William Jennings Bryan in 1896 gained over forty percent of the vote for the Democratic Party. In 1952, Campbell was Dwight D. Eisenhower's third-strongest county in the nation, and in 1964 it rivalled Hooker County in Nebraska and that famous GOP bastion Jackson County in Kentucky as Barry Goldwater’s strongest county outside the South.
