This is awful beyond the wildest nightmare.

And now Dubya says he's going to cut his vacation short to go and view the
damage. That's all they need, a TFR to shut down all the helicopter rescue
operations...

Are you one of those people who likes to take cheap shots at our President
just because you don't like his policies ? Every major news outlet is
reporting that the President is returning to Washington. Even cnn.com says
"Bush was expected to visit the region affected by Katrina, but details on
that trip were in flux as the White House worked to make sure the president
would not disrupt response efforts."

This is a question of the lesser of two evils and the most good.

Does the President stop and take a "land" tour of the area, drawing
precious resources from the recovery efforts?

or,

Does the President do a flyover in AF1 enroute to DC and let the boots
on the ground do their job?

In this case, politics will probably interfer with the job at hand.
It doesn't matter if there is a D or an R after the title.
The President's physically being there doesn't contribute anything to
clearing the debris and getting the infrastructure back in working order.
