So you've won. Here's how you keep it: first, pass strict laws against publishing misinformation and shut down shitspreaders HARD. Do everything possible to put more money in voter's pockets and remind them constantly of that fact. Compare everything the right says and does to Trump. Do the opposite of whatever the US does. Work to remove any leverage the US has over your countries and help each other out.
Full disclosure: I'm a USian. Our recovery depends on the right failing as hard as possible, here and in your countries. There is an international far right movement at work, don't get comfortable and don't think you are safe. Identify their sources, causes, support structures and propaganda channels and shut them down before they can take root. Good luck and godspeed!
