In what way is something that got zero repub votes "bipartisan"?
You're correct - thanks for catching that. I was thinking of the so-called "Gang of 14" compromise to permit some federal judges to be confirmed, but that was a temporary agreement that expired in 2007. The rule eliminating the filibuster for judicial nominees other than the SCOTUS was, as you point out, enacted with no GOP support when the Dems had a slight majority. Of course, the GOP when it retook the Senate retained the rule and expanded it to allow Gorsuch to be confirmed.
The Dems' move proved to be short-sighted - they figured that Hillary would coast to election and the Dem Senate would be able to ignore the minority with ease. Now the GOP is faced with the same decision - eliminate the filibuster rule generally and hope they can retain the majority indefinitely.
