Like all certainties in life, rules in the Senate change. One of America’s most glorified political theatrics, the filibuster, now only exists should the majority party choose. It’s not likely any future majority should acquiesce.When Republicans during the Bush 41 administration considered changing the rules to eliminate the tradition established by duelist Aaron Burr in 1807 and first actually performed by Senator Henry Clay in 1842, Democrats wailed and cried on how “evil Dick Cheney” might consider overriding Democratic party filibusters by changing Senate rules to allow a simple majority to pass Bush judicial and cabinet appointees.Frustrated by that annoying little minority party’s ability to prolong the process of confirming President Obama’s appointments, the Democrats chose to light the fuse on the nuclear option they so opposed when Republicans held the majority.There’s nothing unconstitutional about the move.
