Overdrammatic title. They will vote Maduro out in 2018 if the election is anything close to fair.
Chavez never held an unfair election and neither have the Chavistas under Maduro. Not to say they won't this time facing certain defeat. But they are not dictators so again I don't even know if they are capable of staging a rigged election. Even the Mexicans screwed it up in 1988.
it may not be a 100% dictatorship atm but it is a very authoritarian autocracy, which has shielded itself against parliamentary defeat and has threatened several times, "the people" can't lose or something like that.
