Paul Ryan still opposes abortion with no exceptions for rape, incest, or the health or life of the mother. Mitt Romney isn't willing to go that far, but he has supported a personhood amendment to the Constitution that would effectively make Ryan's position the inalterable law of the land. Here's what you need to know about abortion rights. Supreme Court Justices Clarence Thomas, Samuel Alito, John Roberts, and Antonin Scalia think Roe v. Wade and Casey v. Planned Parenthood were wrongly decided and would overturn those cases. That would return the issue of abortion rights to the states, dozens of which are ready to ban the medical practice. There are five Justices who would vote to uphold Roe and Casey: Elena Kagan, Anthony Kennedy, Sonia Sotomayor, Ruth Bader Ginsburg, and Stephen Breyer.
Justice Ginsburg has only pledged to serve three more years. She's survived two battles with cancer, she's 81 years-old, and she recently fell and broke some ribs. If she cannot serve four more years, and Romney names her replacement, Roe and Casey will be overturned.
People probably think this outcome is unthinkable, but the modern Republican Party is a radical party. Look at Paul Ryan.
