I wish they would work together to get things done.
Only way I can see that happening is for Trump to win then and for the shock of it to cause the democrats to introspect upon themselves and repent and reform. Even this though like others pointed out is maybe futile and hopeless, a "can the leopard change his spots" type thought, but it's the best and only real chance for it. I would argue it's not a totally wild prediction nor longshot chance when you see RFK Jr. and Tulsi Gabbard already turned their hearts and were accepted. More recently too though they won't outright side with Trump even bigtime lefties like Ana Kasparian and Bill Maher are at least not going to shill for the democrats nor defend them any longer and are willing to try to make it work with Trump it seems, and you see them being accepted by the right too.
