“I prefer Steve Forbes and Art Laffer.”
Laffer admits that he voted for Obama. He says he voted for Clinton twice. He insisted that there was no housing bubble, lost a public bet with Peter Schiff over it.
Laffer cultivates the idea that he was Reagan’s chief economist, never corrects interviewers. The truth is he never worked for Reagan, he was already in private practice during the Reagan years. His sole contribution during the Reagan administration was as one member of a large outside advisory group.
Reagan had already learned about Laffer's Supply Side ideas, and Gilder's book just cemented his views. The whole 30% across the board tax cut was modeled on Laffer's concepts and RR had read extensively the ideas behind Prop 13, which Laffer helped design.
So no he didn't serve in the White House, but his influence was profound. Trump is wise to listen to Laffer.
