There is one basic and false assumption: That the POTUS walks into the White House, waves a magic wand and things begin to happen as they command. This is pure fairy tale. Presidential Power that I am describing is a MYTH. American politics is complex, cumbersome and in many ways corrupt. It just doesn't work that way.
If we look back at a snapshot of a few presidents, let's say George Washington, Lincoln, FDR, Ronald Reagan they all spoke in WE terms, not I AM THE ONE terms.
Yet, we, as Americans, WANT to believe in an enthusiastic, charismatic leader that will make all the bogeymen go away. Our belief in the myth help perpetuate the myth. Yet, time and time again we have witnessed in real time that "I, the all powerful mind-set" cannot change anything.
I would love to hear a presidential candidate say: "Here's how WE are going to solve the problem!" Sure, the solutions will be varied and based in different moral and social values. But that's what I want to vote for, not people who think they can walk on water.
Now this is a new thought. I may be wrong. I may have to accept a Baskin-Robbins 31-Flavored set of saviors. I hope not, for our sake.
