Remember when Senator McConnell said over and over “let the voters decide”.
Now he is saying that it will take 60 votes for a Supreme Court justice to be put on the bench. Yes he aims to filibuster any nominee President Clinton or President Sanders puts up.
So be prepared for 9 plus years of an 8 person SCOTUS. I assume their gamble is for Kennedy or Ginsburg to die so they will have conservatives in control. They will then argue 7 is enough like it used to be.
