Ever stayed too late at a really great frat party? One where the music was hot and the people were fun, but they slowly start coupling off and leaving. Then it devolves.
A guy is passed out on the stairs and someone’s drawn on his face with permanent marker. There’s a handful of sloppy drunk people on some beer-stained couches unwilling to call it a night. One of the bathrooms is filled with vomit and there’s trash everywhere. Suddenly a bunch of guys nobody knows shows up because this is the only place where they can keep drinking, and they start harassing the girls that until then were having a great time and now will never come back. Everyone gets into a fight, someone calls the cops and the whole thing ends up being a nightmare.
When the Republicans talk about being the party of Lincoln, remember that party.
