VERY different Supreme Court. No Clarence Thomas
Absolutely! No Thomas confirmation hearing circus either.
I am assuming that President Hart loses in the bad economic times of 1992. In his four years in the White House he gets four Supreme Court appointments. White, Marshall, Brennan and Blackmun retire. I am thinking he brings to the court Lawrence Tribe, Harry Edwards, Ruth Bader Ginsberg and Steven Breyer.
Those are not bad choices at all.
1: You're giving him two exact Clinton appointments.
2: Unless the liberal justices retire earlier so that they can get a favorable successor or have a butterfly health issue, you're going to get only the two vacancies Bush Sr. did. No Thomas is going to change the Court a lot.
You would see a very different Supreme Court. Even if all Hart got was the OTL two seats that Bush had, which turned into David Souter and Clarence Thomas, it brings the Court in a very different direction.
But I believe he would get more.
Byron White, for all that he was a conservative on the Court, wanted his successor to be appointed by a Democrat, and Harry Blackmun I think would have wanted a liberal (Pro-choice) justice appointed to his seat as well.
Here are the candidates I can see President Hart appointing, in order of when they would be appointed:
-Amalya Lyle Kearse, Federal Judge, 2nd Circuit Court of Appeals, to replace Thurgood Marshall (Kearse would have been both the 2nd black and woman jurist appointed to the Court, and from all accounts, Marshall was just waiting for a Democrat so he could leave).
-Mario Cuomo, Governor of New York, to replace William Brennan (Cuomo would be amazing on the Court, and I think President Hart would be firmer in making the case for Cuomo as a Justice than Clinton was).
-Richard S. Arnold, Federal Judge, 8th Circuit Court of Appeals, to replace Byron White (Arnold was a nigh-unanimously beloved and respected judge. For evidence, look at the support he got when President Clinton was considering naming him to the Court in 1994. Arnold's lymphoma would be an issue, but I ultimately think it's one that would be overcome).
-Ruth Bader Ginsburg, Federal Judge, D.C. Circuit Court of Appeals, to replace Harry Blackmun (Blackmun would probably retire late into the Hart Presidency, and Hart would need a nominee who could get through the Senate. Ginsburg had a moderate reputation on the D.C. Circuit, and was well-regarded as a Supreme Court advocate, so I could see her making it through the confirmation process fairly easily. In addition, that would put three women on the Court by the Nineties).
You could also switch Ginsburg and Arnold around in terms of when they are nominated.
That would definitely be an interesting Court!
