Bernie and the Bros. They're the ones who started the crybaby theories against the Democratic party and led credence to the idea that there's some party machine that conspires to make sure that candidates who barely pull 1 fucking percentage point in a poll of polls are somehow squeezed out of sight. Tulsi Gabbard - she's owed nothing.
The ongoing stream of exposés of her very questionable background has convinced her that her cover story is ultimately not going to work, she will eventually have to explain all her bullshit, and that's not happening. Her campaign cannot much longer survive all the investigative work by journalists like
Christine Gralow. In retrospect, it seems terribly naïve that Gabbard thought her façade would hold up through the electoral year when it's already crumbling now.
The truth of the matter....She doesn't have anything at all to contribute besides attacks on other Democrats and making Republicans happy.
