While I believe Krugman is correct in his thesis he is over broad in his application. Obama has done nothing but reenforce a negative image. From "change" to his business as usual reality. He has given away billions in bonuses to bankers destroyed the property valuation market (HVCC), $700 pork barrel stimulus, no jobs, 10% unemployment, and now the black hole/death star of healthcare - which won;t cost us anything. As long as he continues drain the econ, raise taxes and prolong the depression polciies - people will continue to flock to these msgs. He controls the agenda, timing and focus - these guys are mindless gadfly's with the majority of their support coming from the dienfranchised that Obama created.
