he keeps saying that he expects Biden to win. The full context though, has always been that he just thinks establishment is too powerful to fight - he was pretty clear that he would still like Trump to win.

He never had any confidence in US elections to begin with, and only started doubting that when he saw that Trump got in and wasn't a phony.
