It should have been evident to clear-eyed observers that the Republican Party is becoming less and less like a traditional political party in a representative democracy and becoming more like an apocalyptic cult, or one of the intensely ideological authoritarian parties of 20th century Europe. This trend has several implications, none of them pleasant.
In his "Manual of Parliamentary Practice," Thomas Jefferson wrote that it is less important that every rule and custom of a legislature be absolutely justifiable in a theoretical sense, than that they should be generally acknowledged and honored by all parties. These include unwritten rules, customs and courtesies that lubricate the legislative machinery and keep governance a relatively civilized procedure. The US Senate has more complex procedural rules than any other legislative body in the world; many of these rules are contradictory, and on any given day, the Senate parliamentarian may issue a ruling that contradicts earlier rulings on analogous cases.
The only thing that can keep the Senate functioning is collegiality and good faith. During periods of political consensus, for instance, the World War II and early post-war eras, the Senate was a "high functioning" institution: filibusters were rare and the body was legislatively productive. Now, one can no more picture the current Senate producing the original Medicare Act than the old Supreme Soviet having legislated the Bill of Rights.
Far from being a rarity, virtually every bill, every nominee for Senate confirmation and every routine procedural motion is now subject to a Republican filibuster. Under the circumstances, it is no wonder that Washington is gridlocked: legislating has now become war minus the shooting, something one could have observed 80 years ago in the Reichstag of the Weimar Republic. As Hannah Arendt observed, a disciplined minority of totalitarians can use the instruments of democratic government to undermine democracy itself.
