I am a leftist. I'm telling you they call everyone liberals. They even call Trump a liberal.
Liberals are moderate conservatives, a.k.a. Establishment Democrats. And then you have the GOP, which consists of extreme right Fascists, so far right they're practically the antisis of liberal. There is no dominant centrist or leftist party in the United States. The closest we have in office are AOC and Bernie, and even they're just barely to the left of center in my eyes.
Ranked choice voting won't solve everything, but it's a step in the right direction. It's worth giving it a chance.
