The Supreme Court has proved once again that, despite which President chooses them, and their political ideology, that being on the Court has an effect, and causes surprises.
All three of Donald Trump’s appointments (Neil Gorsuch, Brett Kavanaugh, Amy Coney Barrett) have surprised on some cases, so while all are conservative in nature, one sees unusual alliances on some decisions, including being on the same side at times with Democratic appointments (Stephen Breyer, Sonia Sotomayor, Elena Kagan) to the Court.
So no President can ever be certain that his appointments will vote the way he might wish, as Trump has seen that his nominees have not sided with him, including on the claim that the Presidential Election of 2020 was “stolen”!
So it is really a case of unpredictability on the future of the present Court, although clearly, it is still the most conservative Court since the 1930s! Even Chief Justice John Roberts, however, is sometimes surprising in his views on cases!
One point is perfectly clear, however, that Clarence Thomas and Samuel Alito are the most right wing members of the Court!
