The Supreme Court would be very unlikely to do anything that would upset (royally piss off) a large chunk of society. Like you suggest, if anything, they’ll uphold Roe.
And for the record, any kind of abortion restrictions will be a boon for Democrat fundraising. Even a twice as senile old Biden could win a presidential race against any R candidate threatening Roe.
Well, the public is pretty ignorant on the Roe issue. Polls have shown that most people (wrongly) think that overturning Roe will make abortion illegal. It won’t. It will simply mean that some red states with large anti-abortion populations will proscribe the practice. In the blue states, nothing will change. If Roe were overturned (and, again, I’m not optimistic that it will be), I don’t think that the pro-Dem, pro-Biden aftershock will materialize in the way that you predict. Once pro-abort people in blue states understand that abortion will be unaffected in their state, I think that the overall reaction will be muted. I don’t think that Alabama or Oklahoma or Louisiana or Mississippi suddenly swing to the Dems if abortions are banned in those states.
Conversely, if the current SCOTUS upholds infanticide, the backlash will cause conservative fundraising to increase.
They will EXPAND infanticide.
You don’t get to be a black robed princess by having morals, values, and respect for the law.
