All of it revolves around the black man. They just cannot understand how he can be in the White House and be the most powerful man on Earth. He must be brought down with every opportunity. By closing the gov they have taken away a lot of White House staff and they like that.
I'm really beginning to think it comes down to this kind of xenophobia. A twice-elected Obama has forced the reactionaries to realize they aren't
going to win: the future will not
be run by ultraconservative white males. This so terrifies them they'll throw any and everything to the winds to try and avert it.
