voters select these candidates via primaries and general election, though.

Yeah, just look at the DNC and Bernie. Clearly chosen by the voters and not at all manipulated by the party to get the result they wanted.

They’ve literally fucking admitted to it and apologised, and you still eat the Lib propaganda that he lost fairly?

Name calling isn't really in the spirit of this instance. You can argue and still be nice.
