Since 1930, the country Mexico 'holds elections 'every six years' and has 'never been under a 'military or 'dictator’s rule'.

Since then, that is since 1930s, Mexico held elections every 'six years' to vote for their president. But until 2000 each election was one by 'Institutional revolutionary party' (PRI). Opposition parties did competition elections but not at all managed to win as PRI (Institutional revolutionary party) used to cheat, win, and malpractice.
