Textbook description notwithstanding, the President is the Government. That is why he is above the law, can summon MPs to State House and dictate how motions go in Parliament and cause the Constitution to be changed to allow him hire or fire the Inspector General of Police. That is why hapless government functionaries must invoke and intone the name of the President every time they address multitudes.
It explains why MPs only feel important when they address the president directly, take selfies with him and post on social media. This explains why government institutions like EACC, IEBC and the Police that should ideally enjoy a level of independence, are so toothless. It also explains why the President says certain things and not only gets applauded; he gets away with it where no one else would.
