The answer is they need either a constitutional amendment or a supreme court decision because the Roe decision is founded on a constitutional right to privacy. Which is why Trump is packing the courts with zealots. Should ask them about why the Republicans haven’t stricken down abortion while they had a full rule. They can’t answer that. Anyone with a brain realizes the Repubs just use abortion as a boogeyman to rustle voters.
It’s a “get out of arguments” card, basically. No one can argue with these people because they lean on their morality. Anyone who disagrees with them, they equate with murderers. And they then don’t have to pay attention to politics because the R stance is anti-abortion, period. We have seen from numerous examples that Republican politicians don’t necessarily personally abide by the anti-abortion.
