@edgarblythe,
I watched C-Span's coverage last night of the House until after midnight. This morning I have been listening to the pundits. It does indeed appear that there will be a shutdown Monday night. It will cause a lot of people to be inconvenienced and will cost a bunch of money.
But it will probably be short-lived. Tea Party types will be able to say they "stuck it to Obama." Obama can say that he didn't cave and Boehner dodges a bullet.
Most importantly, it probably means that there will an increase in the debt ceiling before Oct 17th. That, in my mind, is the more critical issue as a default would be devastating.
My guess is that the markets will not panic tomorrow about a shutdown.
