I watched from my friends balcony on Av. de Mayo and walked down for the start of the speech, and early in the morning to see the crowd. Definitely some fanatics; people say he has nothing in common with Trump (haha) but the weird messianic imagery their fans occasionally embrace creeps me out. Someone was selling LLA/Evangelical shirts, I include a pic so you see what I mean. (if you cant see they say Leon Juda Vencio)
Also the MAGA hats. Meh. Not a fan of those, or the yellow Gadson flags, which were also out in force.
I was a little surprised he rode in a convertible, right below me. Someone threw a plastic bottle of water from the sidelines, but otherwise no incidents. As an estadunidense, I find an open presidential motorcade on a busy parade route alarming; with all the memetic nods toward USA political imagery, youd think theyd want to avoid that one.
