Same as with the other end of the spectrum.
Every 8-12 years, social conservatives throw a tantrum and DEMAND that a candidate take a "strong" position and say out loud the magic words: "I think abortion should be illegal everywhere."
No matter that no pro-life candidate has done a damn thing to overturn Roe/Wade....it doesn't matter. They just want someone to say the magic words, and then they will vote against Hillary.
