You are putting too much weight in the figure of the president. He is not a king, that's not how it works. The USA is a republic, meaning the president is not a ruler, but merely a ceremonial figure. Presidents don't make laws, congress does, with the former only having veto power. At least that's how a republic is supposed to work, but people seem to increasily view the potus as the supreme leader guiding every single aspect of the country, as if he were more than a monarch.
