Tulsi Gabbard has been slowly edging toward leaving the Democratic Party and, it now seems more likely than not, launching a spoiler candidacy to peel disaffected left-wing votes away from the Democrats. Her “present” vote on impeachment, followed by a disavowal of what she called the “zero-sum mind-set the two political parties have trapped America in,” sets the stage for Gabbard to play the role of 2020’s Jill Stein.

Left-wing anti-anti-Trumpism played an important role in the bizarre 2016 outcome. Die-hard Bernie activists, fired up with anger at the release of DNC emails stolen by Russians that purportedly showed the party had rigged the primary, demonstrated against the party outside its convention hall and tried to drown out the speakers inside with boos. Stein attacked Hillary Clinton from the left, then audaciously staged a grift-y fundraising scheme supposedly to hold recounts in the states she had labored to flip to Trump. Trump’s election appeared to deliver the same shock of reality that had vaporized Ralph Nader’s 2000 support.
