What are we supposed to do about Donald Trump and all the trouble he has caused?

Donald Trump, who has been posing as the President of the United States since January, has caused more problems, fear, and distrust than any President in modern history.

He has made numerous disgusting remarks about women, even admitting to committing sexual assault (without realizing that he was doing so) and he has insulted and hurt gold star families, war heroes, decent public servants, people of color, immigrants, veterans, handicapped people, and the LGBT community (sometimes several in the same day, like today).

What the hell are we supposed to do?
