It's CLEARLY a 10th Amendment issue. Roe was a bad decision. Any subsequent decision that does more than simply overturn Roe would also be a bad decision.
Abortion, like all murder, belongs to the states.
Any "conservative" who argues otherwise is not conservative.
It's more fundamental than a 10th Amendment issue. It's a 5th Amendment issue: No person shall be … deprived of life, liberty, or property, without due process of law. Abortion deprives a baby of its life without due process. The fact that the Feds are mandating its legality is, as you say, a 10th Amendment issue, but the fact that it occurs at all is a 5th Amendment issue.
