The 50% of the population who have just had their right to modern medicine removed for a start. Then the majority (?) who think everyone should not be allowed to walk around with a pistol stuck in their waistband.Win a lot of votes from whom? The people who are enjoying having the Court and, soon enough, Congress, aren't going to budge. If Biden is going to nominate new Justices, he'd have to do it before November for them to be confirmed by the Senate. If not, voters would have to return both the White House and the Senate to the Democrats in 2024.
I really do not get american politics, and I am sure I am wrong, but it seems to me that the SCOTUS is doing everything in their power to make such a platform broadly popular.
