Much of the reaction to the April 16 Democratic Presidential debate was directed at the moderators for focusing on character and perception rather than policy. But issues got mangled as well—not only by the candidates, but by moderator Charles Gibson. While questioning Barack Obama about his proposal to raise the capital gains tax, Gibson claimed that when the rate has been cut, government took in more money, but when the tax was increased revenue fell. Although this argument warms the hearts of the Wall Street Journal editorial page, the implication that capital gains tax rate cuts raise revenues is not supported by the evidence.

Props to Barack Obama for resisting the siren call for a summer gas tax holiday. In contrast, Hillary Clinton has clambered aboard John McCain’s free-lunch bandwagon, vowing to support the gas tax cut he first proposed a couple of weeks ago. Even worse, she’s now tied it to an energy company windfall profits tax so, as she says, oil companies would “pay their fair share to help us solve the problems at the pump.”
