Owing to its history of settlement by anti-slavery Yankees from Iowa and ultimately New England, Doniphan County became a Republican stronghold and has remained so ever since. The county has voted for the Republican nominee in every presidential election since Kansas became a state, beginning in 1864. With Riley County voting Democratic for the first time in the 2020 election, Doniphan County is the only county in Kansas that has never had at least a plurality for the Democratic nominee.Sullivan, Robert David; ‘How the Red and Blue Map Evolved Over the Past Century’; America Magazine in The National Catholic Review; June 29, 2016 Only on three occasions has the Democratic nominee reached forty percent of Doniphan County's vote, all of these in national landslides, and on only seven occasions have the Democrats managed 35 percent of the vote in the county.The New York Times electoral map (Zoom in on Kansas) Doniphan County is one of four counties or county equivalents to have always voted Republican during its history, and of these has the longest unbroken streak of Republican support.
