Politics
For most of its history, Madison County has primarily supported the Republican Party in presidential elections. From 1880 to 1960, the county only failed to back the party's candidate in 1932 when Herbert Hoover was defeated in a national landslide for reelection by Franklin D. Roosevelt. The county was much more of a swing area between 1964 & 1996, voting for the national winner in every presidential election between 1964 & 2004 aside from 1988 when Michael Dukakis was boosted to an inflated margin of victory statewide by a farm crisis. Since the start of the second millennium, Republicans have carried the county in every presidential election. Donald Trump also produced the county's strongest Republican presidential victory since 1952 in 2016, winning by a margin of over 30 percent.
