There’s a wonky, long-running and almost entirely under-the-radar hitch that makes it harder for some women in Maryland to get an abortion. Maryland is one of 17 states that covers the full cost of the procedure for low-income women enrolled in its Medicaid health program — unless the women qualified for the coverage because they were pregnant. The obscure loophole has persisted in the administration of Democratic Gov. Wes Moore, and past administrations of both parties, even after an attempt by the General Assembly to close the gap after the U.S. Supreme Court decision to overturn Roe v. Wade two years ago.
