This is a good and serious hypothetical question that should be asked of all public figures who endorse him, explicitly or implicitly. I'm seeing people being asked: "Is there something he can say or do which will make you rescind your endorsement". But that makes it too easy for them to say: "Yes, there is" without spelling out any specifics. Normally this question is unfair and it is akin to asking "When will you stop beating your wife". But in this case, this is completely justified because the candidate himself boasts that he will not lose support in this scenario.
