Politics
Madison County was formerly an overwhelmingly Democratic county as with most of the rest of Alabama, with only a narrow loss by Al Smith in 1928 due to Prohibitionist anti-Catholicism disrupting this trend until the 1960s. Even in 1964, the county nearly voted against Barry Goldwater due to its opposition to the Arizona Senator’s privatization plans for the Tennessee Valley Authority. However, since that time, the county has become solidly Republican, with the only national Democratic nominee to carry the county since 1960 being Deep South native Jimmy Carter in 1976. In the 2016 election, Gary Johnson had his best showing in the state, carrying 4.05% of the vote. The county is trending less Republican recently, 58.9% in 2004, 56.9% in 2008, 58.47% in 2012, 54.79% in 2016. For counties supporting Donald Trump in 2016, it was the 4th narrowest margin.
