This guy's thesis is nothing more than the false rhetoric the right-wing has been passing along for a while; namely, that Democrats will bring foreign policies that will weaken the U.S.; if Democrats raise taxes on the rich, the rich will "change their behavior."
Never mind that under the opposite policies of the right-wing the country is far weaker, far less prestigious and less trusted than the country Bill Clinton left them. As for taxes, the writer wants us to believe that if taxes are returned to the level under Clinton, rich people won't want to be rich any more because they'll have to pay more taxes. Oh, heavens.
