Do y'all remember H.A.Goodman? The supposedly "left wing" freelance writer for a number of outlets who campaigned hard for Bernie in 2016 and had a big pro-Bernie Youtube channel. He boardcastet every rightwing Clinton conspiracy theory and lo and behold, as soon as the general election came around, he campaigned for Trump. These days he is still campaigning for Trump and is arguing that "Berniecrats" should support Trump in 2020. Yeah, those are the kind of people we are talking about here.
