It’s disingenuous to talk about Maduros popularity without mentioning the brutal sanctions placed on it by the US, which caused the crisis in the first place.
Literally all the people I know from Venezuela, even supporters of Maduro will tell you it started long before. Like 20 to 30 years ago. Even by the period of Chavez, or even before that. I think you don’t know very much about Venezuela. And is very disingenuous state opinions without enough knowledge and lots of ideology.
Venezuela was declining and authoritarian long before the US implemented sanctions.
