The conductors of the debate would be insane to not talk about the economy. The subjects were decided long before this issue came up and can be easily shifted to do just that. We don't need a postponement of the debate at all. This is precisely the time for explaining one's ideas to the public, instead of hiding out in Washington and pretending to know what you're doing.
You're assuming that McCain is going to be hiding out in Washington pretending to know what he's doing. Don't assume anything. There are TV cameras in Washington. Chuck Schumer manages to find them all the time. And McCain knows exactly what he's doing here.
The idea that we need to suspend a debate is an absurd one. All this does is show anyone with half a brain that John McCain is childish, immature, and impulsive in his decision making. The McCain Camp spent several days trying to figure out how to respond to this.
First the fundamentals are strong, then everything's gone to sh*t and we need to drop everything we're doing.
First he's mister de-regulator, then magically when things go awry he's "we need to regulate and fire the bad apples" guy.
Then, an article pops up saying we need to deregulate healthcare just like we did with banking.
McCain had no option left to him (because flipflopping and lying was getting old) but to go nuclear and make a classic McCain move, that is to say, a dramatic and impulsive decision that does nothing to solve our problems but gets everyone riled up for a short time. See: Sarah Palin
