Watch for Hillary to try to step in.
There are rumblings that Bloomingdouche might try, too. But my money's on this whole mess being a strategy for Killary to parachute in as "the last adult in the room" and Arkancide her way to the brass ring.
Gabbard's antics read to me like an attempt to position for 2024, not 2020... every so often, typically as a transition between generations and usually when they know they've overplayed their hand and need to look like they're "backing off", the Radical Left sacrifices its old bulls to make room for those less visibly-Left and thus perceived as (but not really) "more moderate" to pick up the banner, wait for the heat to die down before running it as far forward as they can.
Two steps forward (or as many past that as they can get), then one step back, always maintaining overall movement into Orwellian Hell.
