And delegate well. Because they are at home with their innate stupidity, because they have nothing to prove intellectually, stupid Presidents are comfortable surrounding themselves with people who do the thinking for them. Reagan had Weinberger and Stockman. Stupid Presidents have an instinctive ability to smell a smart idea, even if they could never hope to come up with the idea themselves. And because they are not afraid to surround themselves with superiors, and because, like the best reporters, they are not afraid to ask dumb questions, stupid Presidents end up getting better advice than Presidents who feel the need to intellectually prove themselves to their subordinates.
Stupid Presidents are consistent.
Reagan was undeniably consistent. The Pentagon grasped this, and fashioned a steadfast front against Soviet aggression. The Soviets saw this, and backed down. The investment community saw this, and ratcheted up the stock market to unprecedented levels. The American people saw this, and consumed in record amounts.
