That's Jon Stewart's verdict. I haven't found any reason to disagree.
Posing as a deficit-hawk - "You don't pay for it!" - is easy enough, I suppose. Except, of course, all sorts of government programs get passed, then have the money for them allocated. Bunning's "principled stand" was nothing more than political theater; lucky for America, it exposed how ludicrous the Republican Party in the Senate is.
He has rolled now that the senior members of his party's leadership in the Senate realized how bad he made them all look.
