I have been going near the Embassy of Bolivia a couple of times in the last 10 days, and both times there was a protest/march outside.
I don't understand why Bolivians elections happen in public Argentinian schools, and if this is only in Buenos Aires / Argentina or worldwide.
According to the article, most Bolivians in Argentina will vote for Evo Morales, and this should help him get back in power.
But Evo already served too many mandated, and already made a sly move once to stay longer than allowed (I can't remember exactly the stunt he pulled, there was a documentary on Netlifx about him and about Manuel Correa, president of Ecuador).
That documentary is no longer on Netflix but the episode on Evo is available here:
