The crazy half is in control right now and there’s not much we can realistically do.

That’s defeatist. There is a lot that can be done. You could pressure your representatives to gum up congress so much with filibusters, and unnecessary votes to slow down what Trump can actually get done. You could join the democratic party with others and start demanding that they change from within. You could support local or internet grassroots campaigns who resist Trump. If the only thing you’re going to do over the next four years is wait to vote Democrat again then there’s not much you’re realistically Willing to do.
