The Democratic Congressional Campaign Committee warned political strategists and vendors Thursday night that if they support candidates mounting primary challenges against incumbent House Democrats, the party will cut them off from business. The news was officially announced Friday morning, paired with a statement on the committee’s commitment to diversity in consulting — “which, obviously, is just to give themselves cover,” a Democratic political consultant who learned of it Thursday told The Intercept. The consultant asked for anonymity given their relationship with the DCCC, and the party organization’s professed strategy of blacklisting firms that don’t fall in line.
