That’s not really how election laws work. There are a ton of different things large and small that powerful people can do to distort the equation “people learn what’s going on -> people vote for good outcomes -> good outcomes happen” and a lot of American democracy comes from people making deliberate efforts to try to preserve the functioning of that system. Just having “you can vote” and calling it good is no guarantee of anything at all. People in Russia can vote with secret ballots, for example.
