Abortion is the only really motivator they have for their harpy base. It’s pretty dumb since many of them are past birthing age anyway. Trump is surprisingly wise to not pick an abortion absolutist since Democrats love to frighten women with Handmaid’s Tale imagery to hide their own absolutism to achieve their goals of unlimited partial and post birth abortions.
If a person is so pro-abortion that it is the single basis for their vote, what will pandering do to win that vote?
Trump might support restoration of abortion at the federal level to 16 weeks (he has talked about this multiple times).
But Trump will not support abortion anytime, anywhere for any reason.
A fanatical pro-abortion candidate will still choose Biden, regardless if Trump moderates on the subject.
