Congressional Black Caucus opposes Sanders' requests

[Since I'm the mad scientist proclaimed by myself]

What a clown. Go start your own party and allow everybody to vote. Democratic primaries should be for Democrats.

except that it's practically impossible to create a successful third party. Because of this, the only representation liberals can hope to get is from democrats. Many liberals (especially millennials) do not sign up as members of the democratic party because they dislike both parties. This is not a fair reason to deny someone a voice in the primary process.
