What they arrogantly fail to understand is that just because someone might be a blue collar union member, and generally a natural Democrat, it doesn't mean they're on board with all the radical sh*t that has come to define the modern Democrat Party. Gun control, trannies in the women's room, abortion 5 minutes before natural birth, etc.
I don't doubt that they'll attempt some superficial rebranding over the next 4 years, but their hubris won't allow them to make substantive changes or drag their party back from the Far Left.
