Plus some of the brightest cryptographic minds have already created proven as secure voting systems that are both anonymous (you cannot tell what a certain person voted for) and verifiable (you can make sure that your vote had an influence and was correctly counted). Personally I think that the best system says to hell with voting and rather enforces libertarianism in a totalitarian fashion. The second best system is probably direct overwhelming democracy, which means that everybody votes but laws are only passed if 80% of people voting vote in favor of them.
