1896 was the contest between Republican William McKinley and Democrat William Jennings Bryan.
The electoral map is almost the reverse of what it was in 2024 with Republican McKinley taking the populous northeast and California and populist Bryan taking the south and the western fly over states.

The 1896 election was marked by large financial contributions from the wealthy to the Republican candidate. Interestingly, a major platform proposal of Democrat Bryan, ending the gold standard, was effected by another Republican, Richard Nixon, in 1971.
