I'm far more interested in wondering about the next time a GOP President will appoint A Not Catholic, myself.
Gorsuch*
Gorsuch was raised Catholic and stayed high-church upon switching denominations, so I'm still counting him here.
Gorsuch, while typically siding with religious interests, comes across to me as the least personally religious of the six Republican appointed justices (certainly at least of the five justice Dobbs majority).
Yes, because his mother was powerful and he developed somewhat of a respect for women who work, as opposed to the rest of the sexist clowns.
