Recently, Congresswoman Tulsi Gabbard (D-HI) quit her position as vice chairwoman of the Democratic National Committee so that she could officially endorse Bernie Sanders.
At the time of her resignation, she talked to Wolf Blitzer about the horrific foreign policy positions of Hillary Clinton. She nailed it.
Of course, she is way off on the socialist Bernie Sanders. As Richard Epstein has pointed out, for example, Sanders' protectionist positions on trade are buffoonish.
