@hingehead,
My wild guess is that, according to Latinobarómetro (sponsored by The Economist), appreciation for democracy is falling in Latin America.
Other part of the equation is perception about the handling of the pandemic.
And López Obrador’s popularity beats me. I know it is personal (he’s still seen as an “everyman”, close to the people) and not appreciation for his Government, but still.
I think he has been a terrible President.
