I understand the rules (or at least think I do), and I like them. They have a certain flavor of rigidity to be sure, but I find that restrictions tend to spark creativity. The only real complaint I have against the game as a whole is that, as a restricted anarchy game on Emperor, it's probably unwinnable. But that doesn't mean we won't keep trying.
I agree with JoanK's Chief of Staff idea. To be honest, I'm kind of miffed that I was beaten to the punch, as introducing a "Secretary of War" position was going to be one of my major presidential campaign initiatives.
But as far as implementation goes, I believe the best way to do so is to let the President make his/her own judgments about executive power, rather than write it into the Constitution directly. For instance, my own Secretary of War would receive some share of my Points as president every congressional session in return for his/her advice and commands to the army. I, as President, would ultimately hold a veto if the orders were too ridiculous, but this would essentially be the first step towards forming a true Executive Branch of government, just like in real-life America. In the future, the President's cabinet of secretaries or staff members could expand to any desired size, and we would agree upon a split of the President's share of points each session. This way, each President would have the same powers, but would be free to customize the branch to his or her liking. The only constitutional amendment that might be necessary or advisable is to make these point-splitting arrangements binding, rather than depending on the honor system.
So I am prepared now to announce that I will, as president, have a cabinet of some size. Members of this cabinet and positions available may be announced before the election (which is in two weeks now, if I count correctly), or may be appointed or created after the election.
And as for further campaigning...I'll save that for later. The election is yet far away, and I have responsibilities as Senator. If we can learn anything from RL America, it's that worrying about the next presidential election too early is really, really annoying
