One of the replies to that video says it all:
In July 2004, Republican Sen. Orrin Hatch said there was no such thing. And Republican Sen. John Cornyn threatened in 2008 that if Democrats invoked the Thurmond Rule, Republicans would go nuclear: We could require 60 votes on every single motion, bill, and procedural move before the Senate, he said at the time.
The Thurmond Rule has never been extended back this far. In 2008, Democrats didnt invoke it until the late summer; Sen. Dianne Feinstein said it kicks in after the first party convention. Its February now, and even the longest Supreme Court confirmation in historythat of Justice Brandeis, in 1916took 125 days. (Brandeis was called a radical and bitterly opposed by conservatives, with anti-Semitism even more overt than Fortas later faced.) So this would be an unprecedented expansion of the Rule.
Second, the Rule has never been applied to Supreme Court vacancies. On the contrary, when President Reagan nominated Anthony Kennedy to the court, he was confirmed 97-0 on Feb. 3, 1988, with Sen. McConnell voting in favor.
In short, until this one, an opposing-party Senate has never observed the Thurmond Rule. Not in 1980, not in 1988, not in 1992, not in 2000. There are typically slowdowns in confirmations, but never a standstill. And the rule has never been invoked before the summer, let alone before the cherry blossoms bloom. Perhaps unsurprisingly, were in new territory this year, and at new heights of hypocrisy.
