A single issue? The slaughter of thousands of innocent human babies every day is just a "single issue"?
For most people in the U.S. it is a Single issue. So is Guns, Gays etc. All single issues. You can lump how many babies you want into it to make it seem like a million issues but it is 1 Issue.
Unfortunately, abortion is not a relevant issue any more. We’ve had a pro-life Republican President for almost 7 years with no progress on ending abortion. It’s here to stay, whether we like it or not, it seems. Even Chief Justice Roberts called it settled law, or some such nonsense.
