This time, the aging leftist beat the thuggish reactionary in the rematch. Trump relates very strongly to the Bolsonaro family, so he will be extremely angry. What can we expect from him?
Two things. First, his complaints on the trail about the left rigging elections will become even more shrill. Second, he will begin a pressure campaign to try to force the Brazilian election officials to identify Bolsonaro as the victor. These will probably include more tariffs and even a threat of military intervention.
