Anyone allowed to be in the final running for the powerful POTUS position must hold to the official conspiracy line. How else would the corporate oligarchy remain in power? They wouldn't allow a president to blow their cover because if a POTUS did so the masses would rise up behind such a one and tear the corrupt system apart.

The POTUS must promote the official propaganda to keep the masses in line. The corporate powers will continue to reap great benefit from the war against the created enemy.
