You said Clarance Thomas is Trump appointed. He isn’t.
Every president will appoint judges who reflect their political values (not just in the Supreme Court, but across the judiciary). That’s one aspect of American politics I can’t agree with, separation of legislature and judiciary is (to me) sacrosanct. But it’s part and parcel of the political system there and it’s not a foul move to do exactly what your democratic counterpart would do.
As to Trump getting his SC picks. Well you can put some of the blame for that on Ruth Bader Ginsburg who refused Barack Obama’s request that she retire (SC judges can retire, they don’t need to die on the job, even though they are lifetime appointments). He asked her to go so he could make an appointment of her replacement while he was still in office and ensure a democratic majority going forward, irrespective of who held the presidency . She refused because she wanted to be a judge during the presidency of Hilary Clinton. Obama was also blocked by the Republicans and a wicked but successful move by Mitch McConnell, leader of the senate, that saw the senate refusing to hold the requisite hearings to appoint the democratic pick during Obama’s final year and an election cycle( the name escapes me at the moment of Obama’s nominee, but the fellow is the current Attorney General). So that’s two SC judges Obama missed out on because he was out manoeuvred by both his own side and the other side.
When Trump became president, he got the empty SC seat Obama wasn’t able to fill and within a year RBG died, so he filled her seat too. And he also persuaded another elderly sitting republican SC judge to retire, so he actually appointed 3 young judges and sewed up a republican majority for years to come. I don’t like it, but he did nothing illegal and certainly nothing the democrats wouldn’t have done given half the chance.
