A few things to comment on, edgar -
First, stop lobbing the word 'Nazi'
around. You are using it incorrectly and quite frankly, I find it more than a a little insensitive to its actual meaning and connotations. Further it is unsettling.
While I understand your frustration and anger with what the DCCC is doing, I would ask you to see at least part of, if not entirely their strategy. At this time, the majority of Americans, i.e. the voters are not on the rather recently launched Progressive bandwagon. The idea is to find a candidate who can and will attract the most people to take part in next year's Presidential election, with an aim of defeating Trump or whomever might get the Republican nod should Trump no longer be in office (or should he decide against a second term --- stranger things things have happened). Keep in mind, the idea is long range goals. They are best achieved through small steps.
