Paul Krugman: Cranks on Top

One of the two men who may still have a good chance of becoming the Republican nominee is a scary character. His notions on foreign policy seem to boil down to the belief that America can bully everyone into doing its bidding, and that engaging in diplomacy is a sign of weakness. His ideas on domestic policy are deeply ignorant and irresponsible, and would be disastrous if put into effect. The other man, of course, has very peculiar hair. So don’t let anyone tell you that the Republican primary is a fight between a crazy guy and someone reasonable. It’s idiosyncratic, self-invented crankery versus establishment-approved crankery, and it’s not at all clear which is worse.
