While I'm not a fan of the 60 vote Senate, I generally can't fault Mitch McConnell for doing what he can to gum up the works in that chamber. It's true that the minority party has a choice to make between all-out obstruction versus cooperation, and that the latter has a lot of real advantages (basically, that their constituencies can be considered in policy-making), but at least in my view the choice was made for McConnell by the overwhelming preference of his conference, and he's just been carrying out what they want over the last few years.
Whatever you think of McConnell and the GOP strategy, however, it's certainly clear that he and the Republicans have successfully implemented the 60 vote Senate on all bills and nominations, something that never existed before (and only began to be a real possibility in 1993, the last time before 2009 that Democrats won unified control of both branches). This is a real accomplishment for McConnell, and one he can brag about.
Or pretend that it never happened, as Sahil Kapur notes over at TPM: "Senate Minority Leader Mitch McConnell (R-KY) has embraced the argument that President Obama was able to pass every bit of his legislative agenda in his first two years thanks to large Democratic majorities in both houses of Congress. " Or, as McConnell puts it: Obama "got everything he wanted from a completely compliant Congress for two of those three years."
Yikes! Kapur lists several of the items which Obama wanted but were blocked by the 60 vote Senate, including climate change legislation, the public option on health care (at least a weak form would have had 50 votes), the DREAM Act, the elimination of Bush-era tax cuts on upper income taxpayers, and more. The stimulus almost certainly would have been larger. Moreover, the odds are good that a simple-majority Senate would have passed significant follow-up aid to the states, not to mention more timely unemployment insurance extensions. Now, it's worth remembering that the historic 111th Congress did pass a whole lot of legislation, including a whole lot of what Obama wanted, but "every bit of his legislative agenda" isn't a stretch; it's a flat-out lie.
Oh, and: Nice catch!
