The idea of the unitary executive is not in the Constitution and needs to have a stake driven through its heart.
As a general idea, the POTUS should not be immune. We don't want him/her to be jailed just because the other party doesn't like him/her. But they should be able to be jailed if he knowingly violates the law or exhibits corruption. For example, if the law was they couldn't buy/sell stock, and they did, then remove them and put them in jail (with due process, of course). This blanket immunity is a joke.
Agree with term limits all around (every branch). In fact, on the old TMF I posited the idea of a maximum time of elected public service. Say 20 years. If you're elected dog catcher several times, and after 16 years you are elected POTUS, you have 4 years to be POTUS.
Interesting idea about SCOTUS administering districts. Also, SCOTUS should have a law enforcement arm (I would assign marshals). Right now they have no enforcement arm.
