Historically, like all of secessionist Middle Tennessee, Lewis County was overwhelmingly Democratic. Although it did vote for Charles Evans Hughes in 1916 and Warren G. Harding in 1920, Lewis County would be firmly Democratic for the next six decades, being one of only two Tennessee counties to remain loyal to both Hubert Humphrey in 1968 and George McGovern in 1972. Ronald Reagan broke this Democratic sequence with a 177-vote majority over Walter Mondale in his 1984 landslide, but Lewis County would subsequently remain Democratic up to 2000. Since then, however, like all of the rural white South, it has become overwhelmingly Republican due to opposition to the Democratic Party’s liberal views on social issues.
