With a Supreme Court case looming this week that could strip away the right to mifepristone, an abortion medication used in nearly half of abortions nationwide, the GOP is at a crossroads. At issue is whether the party will hew to the most extreme of positions: outlawing abortion with few to no exceptions, not even in cases of rape or incest, or to save the life of the mother. The few moderates left within the GOP are wringing their hands and warning of electoral catastrophe, while the presidential candidates weave and dodge the issue to ensure they can still appeal to the base while not alienating centrist voters.
