I didn't like her purchase and manipulation of the Democrat party, and abrogating the democratic process in denying the people their choice of Bernie Sanders.
Yeah, from my perspective, it failed long before that. The Democrats couldn't achieve their true objective if they had allowed Bernie to be elected, which was to give the illusion of a better option while ensuring that the status quo isn't affected where it relates to power and wealth.
Bernie was blocked for the same reason Biden isn't trying to block Israel from destroying Palestine.
