If they voted for Trump they were stupid enough to elect an insane asshole criminal who lies all the time and changes his policies every other day. He is a dictator who thinks him and Putin can enslave the world.Trump is certainly polarizing, but I think even your words suggest that this is not normal political polarization. Trump is not a traditional conservative. It has to be acknowledged that he has pulled in different voters into his "personal" coalition. If people want to say his voters are uneducated, fine so be it. However when uneducated blue collar voters were solidly Democratic, no one ever called out their lack of education. Even now, no one points out the Democratic coalition is still underpinned by poor, uneducated voters.
Many Trump voters merely think they have been left behind. Trump's popularity with this voter will not be easy to transfer to another Republican and will likely be up for grabs if the Democrats don't take them for granted.
You would actually find a lot of stupidity within the ranks of Democratic voters. I think you and others impose a certain self-righteousness to your politics. Once you give into this temptation that a certain voter is stupid and let's say doesn't know what is good for them, it's more than divisive. Can't people just oppose Trump the man and his policies without trying to label and denigrate his voters?
