I think you've got your emphasis mixed up. The "when called into" bit refers to the militia. The President is the cinc of the armed forces at all times, and the militia too when it's needed. The text says the president has limited powers. The truth is that the president can do what he pleases to the extent that the congress or the courts do not stop him.
The whole idea of a tax haven or a loophole, is that it is legal. They exploit the letter of the law to avoid the spirit. There is only the presumption of innocence in a criminal sense. This is a political question.
One of the scarier things about the Cheney philosophy to governing was that he knew the judiciary was so slow. In a presidential term of four years, scandals at the very beginning just might work their way through by the end of the first term. Sometimes faster as in Watergate, but usually slower.
The executive also has the huge luxury of using tax dollars and the federal bureaucracy to lean on their political opponents. If they decide to do X, all it takes is an executive order and it's done. To overturn the decision, barring an act of congress, opponents have to undertake the lengthy and expensive litigation. And Cheney chose to litigate EVERYthing, using the entire weight of the federal bureaucracy, stonewalling at every turn, whereas the opponents would be forced to pick and choose court battles.
"Jobs proves CEOs are worth their pay,"
The Jobs-Fiorina comparison makes almost the opposite point seeing as Jobs's salary is $1 and Fiorina's was ~$8M
