States and voters can no more allow abortion than they could legalize slavery. The "send it back to the states" notion is not only bogus, but impossible. Either the woman has the right to choose, or the child in her womb has the right to life. The latter is the only basis for overturning Roe.
This is an issue of constitutional rights, no matter the pendulum's swing. Therefore, Thompson's anti-Roe/pro-choice position is untenable.
What would be a “tenable” position for you then? And don’t refer me to what a candidate BELIEVES about the subject. What could a President DO in the executive office that would make his position tenable for you?
