I think like 54 of the delegates from PA are uncommitted on the first ballot so yet winner only gets 17 guaranteed first ballot votes.
Why have an election?
Voting is now not essential. Voting is for Suckers!
To give the public a feeling that they play a part in this, but the system is rigged to protect their cushy jobs. They will tolerate most nominees so long as they are willing to not rock the boat.
Demmycrats don't hide the fraud, they just have tons of uncommitteds from the start to sway the nomination in case an undesired may be nominated.
