Here is the thing that I find interesting.
Presidential candidates tell us they are going to do a list of things. In almost all cases the powers of the president don't support doing very few if any of them.
A president can't make laws, he can only choose to sign or veto a law that congress gives him.
Some would say, but the president has influence. Maybe, but Oprah has influence too and she's not the president. The thing I hated about the last election was that we had two sitting members of congress telling us what they were going to do when they were president and I was asking myself, "Why are you not pushing that legislation through congress now?" They had the powers to actually get the ball rolling.
If you want drug legislation to change, there again its congress that does that. Congress can pass a law without the presidents signature if they have a large enough majority voting in favor it.
Creating cabinet positions and appointing nominees to cabinet posts is done by the Senate.
In all reality, aside from executive orders to executive departments, the president can only change certain things without congress.
As for giving back land to the Native Americans, I don't think the president or congress would be able to do it. The Supreme Court wouldn't alllow. The only possible way would be eminent domain, where the government would have to pay land owners for their property. Even if it was the size of one or two states, that would bankrupt the government.
Lastly, Milton from the two threads that I've read of yours, I get the impression you would not be old enough constitutionally to be confirmed by the electoral college as the president.
I personally would like to see what kind of damage you could do to a city government first.
