Katrina and the Common Good
For example, it's worth asking why Katrina was such a tipping point for the President's approval ratings....an excerpt from what appears to be an excellent blog within TPMCafe, After the Levees.
The answer is that it offered irrefutable images that he was not looking after the common good. It undermined the average American's self-image of being part of a country that actually worked. Without consciously changing their mind on a single policy, a good quarter of the country just stopped believing in the President.Remember, this change of heart happened mostly in people who were not personally affected by the disaster at all.
