Literally why would you want any system where someone can be elected without majority vote lol. Why do you want the same states over and over being the only ones where voters actually matter? If you are a dissenter in a state, then there really literally is no reason for voting.
50% + (1-.999...)% is dumb to request, because that will almost never happen and then will get passed up to the House and the Senate who just pick whoever they want at that point.
