They've had how long to fix the economy, and now all of a sudden McCain wants to drop everything and try to help, even though;
A - He thinks the fundamentals of the economy is still strong
B - As per Dick's quote, he doesn't know much at all about it.
Reeks of desperation because all of the momentum is with Obama, and obviously with what is happening on Wall Street, he wants the debate to be delayed so he can be more prepared IMHO.
I don't think he saw what is happening this week and last occurring so soon after the Republican Convention IMHO.
