EJ Dionne: “Reagan’s optimism has thus been replaced by crabby put-downs of the less affluent. Perry said it directly in his announcement speech: “We’re dismayed at the injustice that nearly half of all Americans don’t even pay any income tax.” Considering the other injustices in our society, this seems an odd and mean-spirited obsession.

“Tax the poor” is a lousy political slogan. That’s why Cain’s 9-9-9 plan and Perry’s flat tax are doomed to fail. Among conservatives, Santa Claus has given way to Scrooge.”
