He acts like a dictator, and can do a lot of damage since no one will stop him?
A president of the United State of America has it within his granted powers to be quite damaging if he doesn’t have the USA’s best interests at heart. That president doesn’t have to step outside of his granted powers to be “damaging”.
And THAT is the reason why people have to make sure to elect the RIGHT KIND OF PRESIDENT and not one like Obama!
