The primaries are infomercials. The candidates, speakers and platforms are chosen before hand by party insiders and presented to the delegates for a politburo style, made for tv, show of approval.
Try making a peep outside the party line during a primary and you'll find yourself outside just as fast as security can grab your arm.
When this changes, get back to me. Until then... Badnarik.
Uh...sounds like your talking about the conventions, not the primaries.
