A new national survey finds weakening support for and growing opposition to abortion.
The Pew Research Center poll of more than 4,000 adults suggests that less than half of Americans now support legal abortion, with opponents of abortion growing in both strength and conviction.
The poll found support for legal abortion down sharply among Catholics, Protestants, Jews and Americans of all political persuasions since Barack Obama was elected president.
Pew researcher Greg Smith says supporters and opponents of legal abortion also have become more polarized, with about 40 percent of each now saying they don't respect the opposite point of view.
