Of course, if you want more, you could just read Mann and Ornstein, It's Even Worse Than It Looks.
A couple of other things. On the substance, McConnell is correct, as Norm says, about Democratic efforts to block amendments. That's a real thing, and in my view Senate reform should include limits on the ability of the majority party to block individual Senators from offering amendments. I'm not sure how exactly that would excuse Republicans from (say) requiring 60 votes for district judges and low-level executive branch appointments, however. Or, for that matter, circuit and SCOTUS nominees and high-visibility exec branch nominees. Or the abuses of the approval (blue slip) process by which judicial nominees are cleared to begin with (yes, I blame the White House and Harry Reid for reacting passively to those delay tactics, but Republicans surely deserve the bulk of the responsibility). Beyond that, it's pretty clear, as Norm shows in his long list of quotations, that a gridlocked Congress is exactly what McConnell wants.
I do have to wonder, however, that this will buy him anything:
But a guy who, with his co-author, dedicated his last book, “The Broken Branch,” to the late New York Republican Rep. Barber Conable, and who had “It’s Even Worse Than It Looks” receive an enthusiastic endorsement from former Nebraska GOP Sen. Chuck Hagel, is not so easily pigeonholed as McConnell would like.Sorry. I'm afraid that for a party which considers Barack Obama a socialist, palling around with Hagel and Conable are certainly no defense against a charge of being an "ultra, ultra, liberal." Those guys are "ultra, ultra, liberals by current GOP standards; Bob Bennett, who is also cited, was perhaps just a regular liberal, and was certainly a RINO. Sure, that's goofy to anyone outside the bubble, but it's not an argument that anyone is going to win.
At any rate: nice catch!
