Why McCain abandoned his New Orleans trip

Again, yesterday McCain canceled the "oil rig appearance" that was supposed to be his counterimaging to Obama's Germany appearance today.

The official reason for the cancellation was weather (I live in Houston, 240 miles closer to the hurricane, and he could have done it here,) but I think this is the real reason for the cancellation.

And then, improbably, a 600-foot oil tanker collided with a barge on the Mississippi River, creating a 12-mile oil slick and causing diesel fumes to waft over the city's French Quarter. The trip was off.

The entire day was intended to be about attacking Obama on offshore drilling, with the stop in New Orleans likely to highlight the lie that no oil leaked during Katrina..... and then you have the likelihood that reporters would be smelling a massive diesel spill as he said those words......
