The Electoral College does exactly that, dilutes the vote of "the mob", in it's original form the EC could completely ignore "the mob's vote; today EC members are, pretty much, tied to vote the results of the popular vote in their state. Which ignores completely the vote of the opposition; if that's not diluting the vote what is? I was listening to Levin's OPINION PIECE until he started getting angry. Then your opinion piece became angry crap that ran off the rails; why are conservatives so angry?
The founders did not trust "the mob" with the sole authority to choose the "Chief Magistrate", but modern science has proven they should have had more confidence in We The People. Individuals in a mob rarely make the right choice, BUT when averaged together "the mob's" choice zero's in on the correct choice. That's been proven in many studies, many ways; the simplest example is when a large number of people are asked to guess the number of Jelly-Beans in a jar their guess's vary wildly, but, when averaged together the average of their choices is (almost invariably) very close to correct. Before you get hung up on that simple example or Jelly-Beans read up on it, it's quite amazing.
Anyway, I believe in We The People, the Whole American Experiment proves that, as bad as it is, OUR Constitution beats hell out of the next best thing ... EVER ... in the history of the world! IF the Constitution has failings, and the Founders knew it did - hence the provision for Amendments, the one big one is they Founders didn't put quite enough faith in WE THE PEOPLE.
