 Roosevelt was nominated by the convention after agreeing to make another rival, John Nance Garner, his vice presidential candidate, and after some of Smith's Tammany Hall supporters, led by William Gibbs McAdoo, began to defect.In the election that followed, Roosevelt faced unpopular incumbent Herbert Hoover.The onset of the Great Depression, for which Hoover's Republicans were widely blamed, meant that Roosevelt's victory was virtually assured, and in November, he was elected by a landslide.
