Good article - up until the point where he claims the Republicans are the "rogue elephants". To the other side the Democrats are the "rogue elephants", and it's interesting that the author appears incapable of seeing that. A truly irrational person is a rare thing. If you are unable to explain the actions of your opponent in any other way then the fault lies within you, not them.
PS: A basic functional strategy would be to block any Democratic bill in the senate and then pass a poison pill in the house which they can then present as the "only option to avoid default". Instead their only option is compromising in the Senate so they can get enough Dem support in the House to pass something. However, they are still acting like they can pass something in the House and blocking legislation in the Senate.
