When I saw Glenn Reynolds' link to a post titled "Is it His Katrina Yet?," I assumed that it would be about the disastrous flooding in Nashville. Instead, it was about the oil spill. William A. Jacobson documents a horror story of "bungled permitting, delays in response, and understating the impact" and asks,

What will it take for it to be His Katrina? Waddaya think, Brownie?

The answer, obviously, is that Obama will never have a real Katrina, no matter what happens or how incompetent his administration's response. That's because Katrina -- and all disasters -- can be blamed only on the right wing. If it's a natural disaster, it's from Global Warming, which is a result of uncontrolled corporate greed (or, as in the case of Katrina, right wing racist genocide.) If OTOH, it's a man-made disaster, it's also a result of uncontrolled corporate greed. (By definition, uncontrolled denotes right of center, and evil.)

As to government-created disasters, by definition they are impossible under liberal governments, because liberalism by definition is about helping people, not harming the environment or enabling corporate greed. Anything that goes wrong is because the right wing either set in motion the events that created it, or thwarted the liberal attempts to intervene.

From this analysis, it also follows that any disaster that might happen under this liberal administration had its roots in the failures of the previous administration, and was thus "inherited."

Thus, it is not Obama's Katrina. By definition such a thing is impossible.
