What has happened is that the Republicans have decided to attack Obamacare via the appropriations portion. This is pretty much unheard of. If a side does not like a bill, they vote to either repeal it or replace it with another bill. You do not legislatively attack a bill that has already been passed by both houses and signed into law by blocking the money that it is legally entitled.
If the Republicans don't like it, try actually winning an election some day. Perhaps do not pick a trust fund baby with the charisma of a jellyfish and a spine like one too to run for President. When you lose 3 out of the last 4 elections pretty handily (2006, 2008, 2012), you don't get to make laws anymore. It's pathetic. They have been taken over by anti-intellectual charlatans, to run against fake-intellectual idealists. Crazies or morons. Those are the choices.
I root for the shutdown to continue, at this point. I hope we default and credit markets freeze up and our credit rating as a country gets buried under a pile of idiocy. This is all a game to them. We need to rid Washington of this cancer; belligerent, myopic corporate lemmings (R) vs. the sunshine and fascism party (D). The people are completely irrelevant.
