You don't understand our Constitution whatsoever. The point isn't to pick an elite that will govern. It's to balance competing smaller jurisdictions against each other. The entire point ISN'T to just pick one simple figure - 53% want it, it happens. It's to have a whole multitude of differently elected groups that have to come together for something to happen. 60% of the House wants something? Doesn't matter at all if 55% of the Senate doesn't. etc
