Well it was an admittedly speculative post. I don't disagree with what you are saying. It's likely true that good president would also not shake the people out of blissful ignorance any more than a bad one but the difference would be that we'd have a good president. I like your second point, I would hope that the people would not allow that to happen. The president can't really do a whole lot without the congress. I think the answer to your third point is simply follow the money. Constitutional candidates don't attract the big bucks. The people and entities with the money work very hard and invest a lot of dollars to keep as many politicians in office as possible who are willing to bend the bounds of where the constitution says the government should be spending money and passing laws.
