This is well done. In fact, I think the president should go on Larry King and do a Ross Perot thing with the same white board.
People are not well informed about these tax cuts, even rich people who believe that if you make a dollar more than 250k all of your income will be taxed at the higher rate. (Dave Johnson has a nice little primer on this.) Maybe it's the result of years of wealthy interests' propaganda or insecurity or some combination, but when it comes to taxes, people get hysterical and frankly, dumb. So the explainers need to dumb it down.
