1) Hilldog is really a way, way worse option than Bernie
2) At the same time, if Bernie supporters seriously think the correct response is to vote for Trump or not vote, they are ing fools. Clinton is competent, intelligent, way more liberal than the Repubs, and will take care of Supreme Court business.
3) In general people need to be less childish/impatient and recognize that actual change happens with consistent dialogue, protest, and voting in ALL elections, whether midterm, primary, general, local, federal over many, many years, not just freaking out over one dude in one primary.
I agree with you so much on #3. If Bernie people directed even a fraction of their effort for Bernie that they did on Congress, they could make some major positive change. But it's hard for a lot of people to understand there's more to government than a president. I blame our education system.
Err, I don't think only focusing on Congress would solve the problem. People need to become involved in local, state, and national politics in order to really affect real legislative change. The problem is that the way work and wages are nowadays, it isn't really feasible for most Americans to be focused on having a good life and providing for your family and be involved deep enough in politics to understand the issues at the same time.
