Justice Anthony Kennedy’s decision to leave the U.S. Supreme Court has launched arguably the greatest court confirmation battle we’ll see in the next 50 years.

Kennedy is seen as a “swing vote” on key decisions, siding at times with the liberals on the court, but mostly with the conservatives. He was, after all, nominated by President Reagan.

The fight will be fierce. It will get ugly. It will show us just how creative Senate Democrats can get in their vow to fight this nomination to the hilt — if they decide to take it all the way.

I’ll make this prediction, though: If this fight gets as bloody as many of us believe it will, do not expect any of the liberals on the court to leave the bench for as long as Donald Trump is president of the United States.

And let us put down forever any notion that politics doesn’t drive the (a) nomination of a justice or (b) his or her confirmation by the U.S. Senate.
