I think that's a pretty important summation. We don't need "Christians" so much as we need "Christ-like people". (You find as many of those in synagogues, mosques, and among atheists, as in churches.) Jimmy Carter may have actually been the best President we have ever elected, from that point of view. And I am not a Christian in any sense that would be recognized by any church.
Maybe reporters have to start asking candidates ethical questions. Trump would have failed that test miserably.
