Given that ideological division between the two parties has increased since then and given some of the things said over not just the last year but the last 10 years it seems likely that such an appointment will never happen again.
Maybe you are right. The constant evolution of tactics into a
"do whatever it takes as long as I get what I want" strategy is basically ensuring such a situation.
It's a shame, really. Judicial nominations didn't used to be such a contentious issue. It was more or less understood that the president, whoever he was, had wide latitude to staff the judiciary. This worked out even with a generations-long Democratic Senate under numerous Republican presidents. Now it's just become another branch of govt for the parties to battle for control over. The last thing this country needs is for the courts to be politicized to this level in the eyes of Americans. Both parties would do well to respect the fact that if they lose the White House, the winner gets some discretion to fill the judiciary without petty blockades. With that, the president should also respect that if their party doesn't control the Senate, they should avoid trying to install judges that tilt too far towards one side of the ideological spectrum and thus invite resistance. I do believe Obama fulfilled that this time, but we all know Mitch values power over anything else.
