The Know Nothing movement began to disintegrate not long after its 1854 victory, dividing over slavery. Gardner won reelection in 1856 only with Republican support, given in exchange for Know Nothing support for the Republican presidential candidate, John Frémont. Republican Nathaniel Prentice Banks easily defeated Gardner in 1857, and the Know Nothing movement effectively dissolved. By 1860 Gardner had left politics and returned to his business interests; he died in relative obscurity.
