Marc Ambinder heard Rush Limbaugh say something crazed and inflammatory, but instead of responding with snark Ambinder wrote a fascinating article about the current state of play in executive branch preparations for emergency continuity of government. As Ambinder points out, you never know when a Borg cube will show up over Washington, let alone a Cylon sneak attack.
The only thing I wish Ambinder had discussed is the real need for legislative action. I've blogged about this before, so I won't go into detail here...it really is a shame that Congress hasn't implemented the generally very sensible plans formulated by the (post September 11) Continuity of Government Commission. Alas, it's unlikely under the condition of divided government that a party would legislative itself out of the presidential succession chain (and perhaps it's too much to ask Congress to do so, regardless of vague party interests). But it really is a very, very, stupid idea to have the Speaker and the President pro tem of the Senate as part of that chain -- and it's worth noting again that Congress wasn't part of the chain of succession until 1947.
Hey, Tea Partiers! If you think elected Senators are a bad idea because they're contrary to the Framers' design -- how about fixing presidential succession? Surely the Framers wouldn't have agreed to the 20th century version, with its unkosher mixture of two branches of government. If Tea Partiers want a cause with clear Constitutional origins and a real chance of passage, they could do a lot worse.
