You sure didn't win their brains; if they believe Bernie's Snake Oil economics, they have none.
Bernie was the whitest candidate from the whitest state, consequently he performed best among the antifa extremists, college students and the gibsmedats.
Ummmmm, the delusion goes on and on. Sure, Bernie LOOKS like a benevolent old uncle, and he may have some rapport with the non-establishment types,
But rapport is NOT support, by any means. Bernie STILL looks like he would be pretty incompetent if in the same room with Vladimir Putin, or even on the phone with Kim Jong Un. And he would melt under a harsh look from Xi Jinping. He would be in WAY over his head in the company of Middle Eastern heads of state, and even the French may sneer in his direction. And of course, there would be little love lost between Bernie and most of the rest of the Anglophone world. Except maybe New Zealand.
