Juan Guaidó wasn't elected. He and his US backers keep shouting "no, I'm the president" and "yes you are" respectively doesn't make it so. It's gangster capitalism Monroe doctrine to install another Pinochet or Branco.

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.

Venezuela is a dictatorship, not because Chavez wasn't elected, but because once elected, he put his finger more and more on the scales of the elections. He arrested opposition leaders so that they couldn't run effective campaigns. When Chavez died and Maduro came to power, he did more of the same, destroying the independence of the judiciary, and shutting down the opposition legislature.

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.

I didn't say anything about Guaidó.

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.
