50 years ago, when the Supreme Court granted the constitutional right to abortion, the country was far less divided than is it today. Now with that Roe v. Wade decision overturned, roughly half the states have "trigger laws" on the books restricting abortion, New York Times columnist Emily Bazelon tells Ian Bremmer on GZERO World.

From a constitutional perspective, Bazelon says that abortion decisions today depend "on what you think of the idea that abortion is fundamental to women's liberty and equality" — a hard sell for what she calls a "maximalist" conservative majority on the court.
