Come on. Kennedy was like a wind sock. He was not very reliable. Getting someone solid and younger on there would be a big deal. It would make that 5 not only reliable, but long lasting.
Kennedy was worse than a windsock.
I distinctly recall an interview he gave to someone on NPR years back (the link is probably lost). He smugly declared he KNEW he was the swing vote, and he freely gave it to whichever side invited him to the best cocktail parties.
I agree with you that this would solidify a 5-4 majority on the court. Now if Ruth Baader-Meinhoff would just cash in her Civil War pension and slink away, there'd be a 6-3 SCOTUS for a generation to come.
But, while this is tremendous news, there is NO guarantee that any nominee DJT picks will see a vote come up in the Senate. The GOPe will, as always, cringe and bow to the hysterical demands of the Left. Always have, always will.
