As a Brazilian living abroad, I can easily see some parts of the right-wing social media bot armies, partly sponsored by the current Brazilian administration, supporting Trump.

Which is rather interesting as there is a close alignment between the goals of Brazilian and American administrations. By supporting the current Brazilian government, the current US administration is supporting its own president's reelection.

As a side note, it was the previous administration that condoned and supported the coup that ousted the left-leaning government. Fun this always happens before Brazil (or Chile, or Argentina, or anyone else) can become a regional power.
