Politics
Initially a strongly Democratic anti-Yankee county, Marion County has undergone two transitions. Between 1912 and 2004 it was a perfect bellwether apart from the Catholicism-influenced 1960 election when substantial anti-Catholic voting by its largely southern white population caused it to support Republican Richard Nixon. Since the beginning of the twenty-first century it has voted consistently for Republican presidential candidates.
