Mr. Bragg sees this quixotic quest against the Trumpsters to be his ticket to become a tremendous liberal hero, however.
Even when he fails, like Anita Hill and Blasie-Ford did in spectacular form, he can get a huge job in Washington, a huge book and TV deal, maybe even a job in the US Senate , WH or Supreme Court.
There is no negatives for him. Even if he were to be sued on this, the City taxpayers will pay his expenses and judgments.
My guess is that he is going to do it, because its the right thing for HIS career.
