Is RNC Chairman Reince Priebus acknowledging that the Republicans have a rigged system? And that "everybody" knew it?
Looks corrupt to me. Why would the RNC set up a rigged system? Is it about money? What is the difference between the RNC rigged system and Bernie Sanders hired protester thugs? ...certainly following the money in both cases.
The "system" Trump is complaining about actually are multiple state systems, and were set up by state GOP organizations, not the RNC. In fact, the RNC passed a rule requiring that if a straw poll vote is held, it must be binding on delegates.
