I'm sorry what? NOT a democracy? Oh thanks for saying, we already knew that genius. It's been flipped on it's head by illusioned and power hungry republicans, white supremacists, and conspiracy theorists.
more accurately we're a democracy/constitutional republic hybrid. The act of electing officials and voting on state laws are both the democratic parts, while state and federal officials passing laws on behalf of the people is the constitutional republic part. Get it right or GTFO.
