So saying something is established, or settled, law means it can't be overturned? Larry, it's been a while since either of us has taken a civics course, but I believe the entire purpose of the Supreme Court, as an equal branch of the federal govt, is to either confirm or overturn existing law.
So, by definition the SCOTUS can categorize an established law as unconstitutional. There's no statute of limitations on which laws they can review / overturn and which laws they can't.
What that means is that saying Roe v. Wade is (or was, now...) established law in no way says anything about how they would rule on it should they be on the court and Roe v. Wade were to come before the court.
Libs hear what they want to believe. So for them, the meaning of a statement similar to what you posted means, to them, that the SCOTUS nominee would not vote to overturn Roe v. Wade. It's nothing more than what they wanted to believe, not what was being said
Now, to be fair, and were you to do some digging, you might be able to find a dem judiciary committee member who tried to pin them down a bit more. If that had happened, I'm sure the SCOTUS nominee would have simply invoked the ‘Ginsburg rule’, which the Notorious RBG became known for, after saying this:
“A judge sworn to decide impartially can offer no forecasts, no hints for that would show not only disregard for the specifics of the particular case, it would display disdain for the entire judicial process.” (https://apnews.com/article/gay-rights-ruth-bader-ginsburg-confirmation-hearings-amy-coney-barrett-us-supreme-court-b9)
Of course the biggest takeaway from the Dobbs ruling is that the libtard media told the gullible sheeple (meaning those who only know what they know because they believe everything the lying media tells them to believe) that the SCOTUS ruling made abortion illegal. It absolutely did no such thing. What it did was establish abortion as a state issue, not a federal right. But you knew that. (yes, I know it's not as binary as that may make it sound, but this is after all just imgflip and there is a character limit on posts...)
I would say that republican lawmakers would fall into the same stupidity trap on an issue of similar importance to them. I guess we'll get to find out once a Dem POTUS nominates someone for SCOTUS and the republican judiciary committee member asks them if they consider Dobbs v. Jackson to be established law. There's idiocy and hypocrisy of both sides Larry...
