As Kevin Drum documents, Donald Trump's position on abortion is evasive, incoherent and it changes hourly. And of course, if you don't like his answer to a simple, direct question then the fault is with the questioner.
Ben Carson even said that "I don't believe that he was warned that that question was coming, and I don't think he really had a chance to really think about it." Because why should a guy running for the highest office in the land expect someone will ask him about one of the five most polarizing issues in the country today?
