Conservative politics were objectively wrong, but people didn't like being told that. They found by allying with other wrong groups like religious fundimentalists, gun nuts, and more recently neo-confederates, neo-nazis, incels and whatnot they could form an effective voting coalition. They don't like each other, but they are very consistent about party above all else to move forward because otherwise they risk total domination. Democrats and Indepentants refuse to do that partly because many of thier ideals are acceptable, it's just the degree to which they get pushed.
