No chance. He’d have no support from the radical left or right. The economy would fall into a shambles.
There would be an intense investigation into his background. Where was he during his teens and 20s? Did he like beer? Did he put mustard on his hot dog or ketchup? Is he pro-prostitution for defending them and allowing them into the kingdom? What about murderers? Child molesters?
Will he support and defend the Constitution or will he be like a Hebrew National Hot Dog and “Answer to a higher authority”. Fox spews and the ACLU would have a field day.
That said… If he pulled off some really fancy miracles like finding homes for the homeless, reducing atmospheric CO2 to pre-1970 values, bringing water to the desert, or initiating world peace he’d have a small shot at – if he posted the proof on all the social networks.
