The US calls Maduro a "dictator" despite being elected. The reason the US does is simple: money (which uses US ideological politics as a means-to-an-end), since he specifically stated his purpose after the death of Chávez: "Compatriots, I am not here out of personal ambition, out of vanity, or because my surname Maduro is a part of the rancid oligarchy of this country. I am not here because I represent financial groups, neither of the oligarchy nor of American imperialism ... I am not here to protect mafias nor groups nor factions. IOW, because he wouldn't sell-out his own people or his own country, so he's been marked for death/removal, his people marked for sanctions, and Fox News leads the charge smearing the man and the country to make some vampiric rich Americans more money.

I stated that Venzuala was another example where "It is similar I think to the situation in the US where poor people will sometimes vote against their financial interests to support an identity."

In Venezuala's case: poor people would rather support unsustainable state subsidies and industries, at the long term cost of running their economy and currency into the ground.

Venezuela is a dictatorship whether or not Guaido won the last election. It's a dictatorship because the government took enough steps that it was impossible for anyone but Maduro to win.
