McConnell did ditch the filibuster rule for Gorsuch.
Kennedy was always the swing vote, so replacing him with a real conservative will have a dramatic impact. My dream is to have President Trump replace Clarence Thomas (who has hinted at retirement), Ginsburg (85 years old), Breyer (80 years old in August). This would leave only Sotomayer and Kagan as true liberals on the USSC, with a sometimes wobbly Roberts as the new Kennedy. A solid 6 conservatives could stop the “judge made law” madness for the next 20 years.
