Agency' (see link)...and an excerpt...
-------------------
"U.S. Catholics were slightly less likely to support legal abortion than Americans overall. According to 2019 Gallup polling, 25% of Americans think abortion should be "legal under any circumstances," while 20% of Catholics take that position, according to Monday's poll.
But while 21% of Americans believe abortion should be "illegal in all" circumstances according to the Gallup poll, only 11% of Catholics think so."
------------------
Suffice it to say, the percentage of Americans who support a complete ban on abortion is, while not zero, definitely small....varying from 15 - 21% (Gallup...see my previous post) to 8% (PEW Research).
