I have said many times, and I will say again here, that Paul Krugman¹ is the most intellectually dishonest person I have ever encountered. One aspect of his dishonesty is that he imputes bad motives to those with whom he disagrees. Read this. Krugman says that Republicans are trying to push the economy "over the edge" to catastrophe. This is vile. Republicans are obviously trying to make things better, just as Democrats are. They simply disagree about means. Democrats think the solution is to spend more money (thereby raising taxes or increasing the deficit); Republicans think the solution is less spending and lower taxes. Both sides are well meaning, but Krugman can't acknowledge this. He demonizes those with whom he disagrees. This, sadly, is a common tactic among progressives, who seem unable to engage arguments. Instead, they attack persons.
