Richard - not speaking for Brian, but if the money is gone well before November 1st it will be a big win politically for Obama. He is one of the best DC-marketers I've ever seen and they'll have this in front of the media in 2 seconds. There will be enough political clout on this one, and media coverage, to get more money passed through the House(s) without hassle.
But, the second batch of bucks will probably not have the same affect and they might have to open the requirements some more.
It just all depends on if the money runs out early and if no other political issues surface.
