If we could somehow "fix" voting (in many or all cases this is a constitutional modification, no simple task), why would we even keep voting at all? Voting's just bad. The things that you and everyone else like about democracy, ironically, have nothing to do with voting. You like the idea that any small child, boy or girl, can grow up to become president. That there is no ruling caste, and so on. That we have peaceful transitions of power from one administration to the next. That there is some sort of time limit on how long one can hold office.
All these things are achievable in a superior system: sortition. Everyone who qualifies (35 and up, no a felon, natural born citizen) has an equal chance at becoming president (similar for other offices). We do 20 or 30 drawings so that if anyone rejects, we go on to the next.
Trying to fix voting when the fundamental flaw with it is that all of us, to the last, is simply not intelligent enough to cast a vote wisely, can't be fix with vote diddling and runoffs and ranked choices and whatnot. The defective portion of the mechanism's still there.
