Three Supreme Court judges were appointed in less than 45 days including Ginsburg herself. And the precedent since if I remember right 1888, maybe earlier, is that no nominations happen in a presidential election year where the president is of one party and the Senate is controlled by the other party.McConnell used the so called "Biden Rule" to support his refusal to give Garland a vote. The so called Biden Rule was a speech Biden while chairman of SJC made in front of the Senate even though there were no openings on SCOTUS at the time where he stated his belief that there should be no vote on a SCOTUS candidate in an election year That's what McConnell used to help back his refusal to vote on the Garland nomination
So if the so called Biden Rule was a basis for the Garland nonvote in 2016 why doesn't it apply now? What's the difference between two events?
The reps are in a tough situation. Rush through a new appointee just ahead of the election and risk losing control thanks to a huge female voter backlash or try to ram it through post election in a lame duck congress after it loses both Senate control and the White House.
The GOP has a lot to lose in November.
