As quoted in "Kurt Vonnegut's 'Stardust Memory'" by Harvey Wasserman in The Free Press (4 March 2006); in actuality, Hitler also wasn't elected by a clear majority vote. Although the Nazi Party was elected to the largest number of seats in the Reichstag, it did not have a majority, and could only form a government through a coalition. Eventually, Hitler was appointed as Chancellor by President Paul von Hindenburg, and used that position as leverage to gain dictatorial powers.
