Three things jump out.
1) The growth of forced cloture has its roots in a long term Republican senatorial minority. They owned it from the beginning.
2) The Democrat's skirts are not clean. From '81 on, at times when they were in the minority, they have been about as involved as the Republicans in forcing cloture votes.
3) Since 2007, we are in a new realm of filibuster and cloture. This is clear - and the reactions of the Repugs at the SOTU last night bear it out - all they are interested in is making Obama fail. To hell with the country.
What a bunch of god-damned corporate-internationalist traitors.
