While Hoover had won a greater percentage of the vote in 1928 (as did Harding in 1920), the national swing of 17.59% to the Democrats impressed all who considered the distribution of the vote: more than one-sixth of the electorate had switched from supporting the Republicans to the Democrats. Only once before had there been a comparable shift, in 1920, when there was a 14.65% swing to the Republicans (while there had been a swing to the Democrats of 13.6% in 1912, this was from a three-candidate election).
