Approximately half the country loves Thomas, and agrees with him. The fact that the perspective of each member of the Court is effectively frozen in time when they are appointed is intentional.
I don't know where you get 'half the country loves/agrees with him', other than the (incorrect) assumption that the population of the country is divided 50/50 along party lines (no Republican president has won the popular vote since 2004, and only once since 1992)
Clarence Thomas is notably the least loved justice in a historically hated court
What is the “popular vote?” You mean adding up the state-by-state votes which is a number nobody is trying to win?
And if we are talking about numbers that don’t matter, republicans won the Congressional popular vote four of the last seven times (by three million votes in 2022) and are on pace to in it again.
You can also look at the generic congressional ballot polling, where republicans regularly are ahead.
Don’t make assumptions about what non-voters prefer. Lower propensity voters lean right these days: https://hbstrategies.us/trumps-non-voters/ (“Within this lower propensity segment, the respondents favor Trump over Biden by 12 percentage points, 50-38%. The unit would prefer a Republican Congress by a 50-41% margin, and Republicans would enjoy the five point identification advantage.”).
So, Thomas's perspective comes from an era when bribery and collusion with monied interests were accepted and normal?
The recent controversy around Thomas's behavior did not spring up because his opinions on governance date back to his appointment, but because--to the outside observer--it looks like he is perfectly comfortable with selling his opinion to the highest bidder. Lifetime appointments are supposed to keep judges aloof from external influences, but it seems like that logic failed in this case.
My apologies, but I decline to argue this point. Whether Thomas (or any other Justice) is a good person or correct in their rulings isn't germane to the point I'm making.
Of all the currently-service Justices, the only one who has deviated from the perspective of the President who appointed them would probably be Roberts - and that statement is mostly based on a single ruling. It's not like he's well-loved by the left.
