I wanted to find out which presidential candidates scored the highest percentages in each state, from the beginning of time through today. Some of the results may be surprising. Without further ado...
Andrew JacksonTennessee (95%), Missouri (100%), Mississippi (100%), Alabama (100%), Georgia (100%), Illinois (68%, beating Harding by 0.2%), Indiana (67%), North Carolina (85%), Virginia (75%). He was the hero of the frontier South and West. It also didn't hurt that in several states- I think you can guess which ones- he was the only candidtae on the ballot.
Abraham LincolnKansas (79%), West Virginia (68%, beating LBJ by 0.3%). In the midst of civil war, many Lincoln-haters in these states were off in the Confederate Army, or refused to participate in United States elections. Thus the electorates were overwhelmingly in favor of the "National Union" ticket.
Horatio SeymourKentucky (75%), Maryland (67%). Majorities of voters in these former slave states had backed the US over the Confederacy, but now that the war was over, they voted against civil rights.
Ulysses GrantNebraska (71%, beating Reagan by 0.1%). Shrug. A state settled mostly by Republicans voted overwhelmingly for a Republican President winning a landslide.
Grover ClevelandFlorida (85%). In an era marked by rampant vote fraud, a Democrat did particularly well with no Republican on the ballot, against a Populist who was despised by the state's rulers.
William Jennings BryanMontana (80%), Idaho (78%), Nevada (81%), Utah (83%), Colorado (85%). Silver-mining states loved the pro-silver candidate in an election year dominated by the issue of silver.
William McKinleyNew Hampshire (69%; he and Reagan polled exactly 68.66%, but McKinley gets the "victory" because Bryan ran much worse than Mondale), Vermont (80%). The other side of the coin. What helped Bryan in the West hurt him in the Northeast, where he was seen as a crazy hick.
Theodore RooseveltMinnesota (74%), Oregon (67%), Pennsylvania (68%), South Dakota (71%), Washington (70%). Westerners loved the "cowboy" Roosevelt, especially since he ran to the rhetorical left of his Democratic opponent. GOP stronghold Pennsylvania hated free-trader Parker.
Warren HardingIowa (71%), New Jersey (68%), North Dakota (78%), Wisconsin (71%). States with large numbers of German-Americans and farmers were in revolt, thanks to Wilson's war against Germany.
Calvin CoolidgeMichigan (75%), Maine (72%). At the height of the Roaring Twenties, auto-manufacturing, Republican Michigan loved the incumbent Republican, and so did heavily Republican Maine.
