This should do the trick in South Carolina.
For everyone else, here's another little item that seems to never make the news: In 2015-2016, Sanders' chief campaign strategist was Tad Devine, who, in concert with serial grifters Paul Manafort and Rick Gates, had worked as a media consultant for the now-exiled, wanted-for-high-treason Ukrainian president Viktor Yanukovych. Devine continued to beg Manafort for yet more political employment until just one year before joining Sanders' campaign; he also briefly worked for its 2019 incarnation.
Unfair it would be to accuse Devine of supporting the brutal Ukrainian autocrat once he became such. With that grisly occurrence, Devine left. What troubles is that he was so willing to work with overt sleazebag Manafort.
And yet Bernie Sanders hired him. Twice.
Perhaps it was Tad Devine's glitzy media idea to propose a dozen or so vastly exorbitant federal programs, à la Huey Long, or maybe Viktor Yanukovych, absent any fussing about their present affordability. Or future finance base. Or realistic, political possibilities.
One is reminded of President Reagan's reply to OMB director David Stockman, who had told the former that his tax-cutting scheme would not, in fact, raise revenue, but slash it, and thereby create a massive (for then) budget deficit: Oh well, maybe it'll work out, said the Gipper. Uh-huh.
