Reactionary Republicans — notably Rush Limbaugh — condemning the Senate’s limitation on filibustering as unconstitutional have, once again, displayed their colossal political ignorance. There is only a single clause, “Each House may determine its own rules,” (Art. I, Sect. 5) remotely concerned with filibusters, and it neither approves nor disapproves of them. The Senate’s action on filibusters was undeniably constitutional to anyone with high-school reading comprehension.
