If you mean Trump would be able to ram through Congress anything wants dictator-like....maybe. But more likely he'd get some stuff through and a lot of stuff held up by Congress. The public, who are not all Republicans, would have a voice in that as well.
But the real damage Trump would do would be his actions as a boorish lout as well as outright ignorance of the constitution and normal rules of protocol on the international scene.
He'd be literally like a bull in a china shop. He might not wreck everything, but he'd do a lot of damage. Not just hard damage but damage to the image of the country. For the country to be run by a bozo of his magnitude would diminish the country in the eyes of many people, Americans and foreigners.
As bad as King Barack is perceived here and outside the country, Trump would do bad in a different way.
Not a Trump supporter, but Obama is not ignorant of the constitution, he has just ignored it. Even when his actions have been ruled unconstitutional he just says so what and presses ahead. The constitution has become expendable unfortunately as long as the legislative and judicial branch do not enforce it.
