Say what you will about the 2010 deal to extend the Bush tax cuts, which helped to set up what we’re seeing this month. But there was definitely a virtue in getting it done by early December, allowing for a productive lame duck session that repealed Don’t Ask Don’t Tell, passed the New START arms reduction treaty, and several other measures. Because this entire lame duck has been consumed with fiscal slope negotiations, and really only the tax rate and social insurance part of it, bills that might have had a chance to pass through Congress if the pipeline were unclogged instead remain dormant. And unlike 2010, the bills in question in 2012 are more of the must-pass variety.
