What is important is the next steps. It is obvious that the left will not win unless we are unified. Go volunteer, use these next four years to try to create the Democratic party you want to see. Make them reliant on your help and use that to push the items you are passionate about. Or you can sit on the outside and watch this country fall while complaining that the people who are actually doing something aren't doing enough.
Yep, if you don't have the courage to sacrifice something for a cause bigger than yourself, that is your choice. Just don't shit on the people who are trying to push the USA in a better direction.
