Your "most Americans who like it that way" (aka the pollz) have not heard about any but an artfully constrained set of facts about Terri. They do not know about the looniness of Felon. They do not know about the belatedness of the "recollections" of HINO and the family and its timing with respect to his collecting insurance. They do not know what he promised to do for Terri and then reneged on. They do not know about HINO's adultery.
In other words, they don't know Jack.
Actually, they don't know Terri Schiavo at all, or care.
Their position was asked as a general statement.
"Who should in all cases be the one to make decisions for someone who can't do it for themselves?"
You can't base the law for all of us on what is best for one person in one unusual case.
