You can polish the turd all you like... But to be in a position to become SCOTUS without an unequivocal position on LIFE hardly brings confidence.
As someone who has read his opinions and even appeared before him, you've got nothing to worry about. You're looking at the specific issue of abortion as the only reliable indicator of where he would stand on that issue. In fact, the core of his judicial philosophy -- everything he's been ever since he's been on the bench -- is the antithesis of Roe. He will oppose Roe not because he's anti-abortion personally (though he probably is that as well) but because the legal reasoning behind Roe is absolutely indefensible for someone who sees the law as he does. He has never once swayed from holding that the Constitution should be interpreted as it was meant when it was written, focusing on the text. Roe simply cannot be defended on that ground.
And Roe doesn't even make it on stare decisis. In the legal sense, "expectations" means that behaviors have changed based in reliance on law -- that there will be ancillary effects from repealing a law that didn't exist when the issue was first decided. A good example of that are the decisions that have given so much power to regulatory agencies. As wrong as they were, much of our legal and economic system is built on the foundation of the regulations and procedures implemented since those decisions. If you tossed all of that out by saying "every single bit of existing federal rulemaking is unconstitutional", you'd have a whole lot of severe ancillary effects that would go beyond just eliminating the power of those agencies. The best you could do is eliminate that authority moving
forward.
In terms of abortion, that means that any decision would have delayed implementation so that it wouldn't affect women who already are pregnant. And, of course, there is the even bigger issue that reversing Roe does not actually outlaw abortion. It would simply return it to being a state issue, so stare decisis would be even weaker.
