The problem is that most of the voters who show up to vote, and whose votes aren't being repressed, aren't going to care that much about most of these issues. Many of the voters who are now being curated as the only voters have no real objection to extreme abortion bans, the end of birth control, interracial marriage, or gay marriage. They are about to die, extremely conservative, rich and know they won't be affected, or all three. I saw a viral tweet bragging about how interracial marriage is "a fight we can win." That this is already being framed as a fight - a fight that a media that would sell their entire family to be able to bathe Trump's feet would absolutely love to dive into - shows you which side has "won." It would also likely be used as a wedge issue, gleefully, as many non-white voters also oppose interracial marriage for various reasons.
Some who might be concerned are still swayed to media coverage that downplays all of these concerns. CNN, for example, ran a huge headline about Cruz grilling Brown on CRT. The ugly smears against her and the callous way she was spoken to don't matter to them. Secretly, I imagine many of them get a kick out of seeing her degraded.
I think a number of Democrats do know how out of control SCOTUS is, but there are no solutions in place to deal with it. The real solutions were if those we were so often told were wiser and able to get through, like RBG, had retired at the proper political time.
