In other words, I find it hilarious when advocates of 3rd parties complain about party insiders having undue influence in primaries of major parties and yet can't explain things like this very thing when I ask them about their third party of choice. How are these delegates chosen?
Apples and oranges. The Green and Libertarian parties never promised their supporters and members that their presidential tickets would be totally decided by some kind of open/public primaries, where whoever "wins" the most popular votes is nominated. Your Democratic Party political machine, on the other hand, did repeatedly make those promises to its voter base. In reality, the DNC decides who is nominated -- they simply rig the process in favor of whoever they want as the presidential candidate (e.g. Hillary or Biden). The Green/Libertarian party way of doing things is, in fact, far more honest.
