He's better off using his current influence to endorse and campaign for someone that he likes the best and then getting some sort of job in an administration if they winA lot of Bernies appeal was he was the only non-Hillary option. That not being the case leaves very little base of support for him. If you were with Bernie because he was left of Hillary well guess what you have a ton of options now. If you were with Bernie because you wanted to be part of a movement well you have Beto now. Bernie doesn't stand out in a field like this.
