I don't swear (in the sense of alliance) to anyone but Jesus, and I let him down daily. We as conservatives know the weakness of the flesh/soul of humans, so we should not hold anyone as infaultable. Not Trump, not Cruz, not even my Roy Moore. That said, we are to judge rightly (not on rumors driven without foundation of proof) and try to pick the best we possibly can, even if that means "none of the above". Plant you center of gravity on conservative Christian values, and if anyone has a problem with it, it is their problem, not yours.
