Reid and Obama have their way with the rules.
For all the gnashing of teeth over the lack of comity and civility in Washington, the real problem is not etiquette but the breakdown of constitutional norms.
Such as the one just spectacularly blown up in the Senate. To get three judges onto a coveted circuit court, frustrated Democrats abolished the filibuster for executive appointments and (non–Supreme Court) judicial nominations.
The problem is not the change itself. It’s fine that a president staffing his administration should need 51 votes rather than 60. Doing so for judicial appointments, which are for life, is a bit dicier. Nonetheless, for about 200 years the filibuster was nearly unknown in blocking judicial nominees. So we are really just returning to an earlier norm.
