Watch from the 40:42-49:28 timeslot: Too Long Didn't Watch version AKA What I originally meant to reply back to you but I never got around to until now: 1. Immigration. In 2016 Bernie was on the same page with Trump being against illegal immigration. Everyone is familiar with Bernie's classic line from 2015 "Open borders? That's a Koch brothers proposal": Spoiler In 2020 Bernie flipflopped on the issue basically co-signing open borders & offering free healthcare, Amnesty and other goodies for illegal aliens. 2. Woke identity politics. In 2016 Bernie was strongly against identity politics and regularly got criticized for it by HRC/establishment Dem supporters & the corporate MSM. In 2020 it felt like he gave in & went along with it.
