Voting registration should require proof of residence, a social security card, and a photo ID driver's license (if you are not allowed to drive or do not drive, most, if not all states issues an ID type driver's license).
Voting itself should require the same thing.
The polls should open at 6AM and close at 9PM, local time.
The news should be strictly forbidden to report ANY returns OR exit polls, under penalty of permanent loss of broadcast license by ALL involved, until 12 hours AFTER the polls have been closed.
