Germany
Adolf Hitler elected
After framing (or at least that is what is thought by many) the communists with the burning of the Reichstag, Hitler demanded the dissolving of freedom of speech and of the press. This allowed nazi propaganda to take the ultimate position. An election followed in which Hitler won (not without the use of intimidation). Hitler than instituted the enabling act which gave him dictitorial power.
