The DNC establishment elite started drinking their own shill media Koolaid that said Biden had the best chance against Trump because a) "Rust Belt" b) "white" c) allegedly has penis d) wasn't as batshit fucking insane as literally every other candidate during the primaries.

Usually candidates moderate as the general election nears, but Biden has taken the exact opposite approach adopting a platform that is in many ways even further left overall than Sanders' or Warren's.
