As for the original question, what's next for her - I hope nothing. She's got nothing to offer anymore and should just disappear from the political scene.
One need to look no further than election night, to get a glimpse of Hillary's cowardice. She couldn't even come and address her own supporters, people who'd given a year of their life to campaign for her. Instead she sent Podesta to Javitz center, and Podesta comes out and says "as far as we're concerned the election is still on, a lot of states are too closed to call, what we want is for you to go home, we will be here in the morning counting overnight", right as she's giving her concession speech.
Hillary didn't even have the guts to face her core supporters. She's a coward. And a hypocrite.
Her supporters claim she should have president because she's fought all of her life for us. She's not done anything. She named a street and a building when she was a senator and she destroyed the Middle East. She didn't even care enough about you to be able to come on stage and say thank you and goodbye. She deserves nothing.
