"Evangelicals in the governing coalition need to find ways to demonstrate that this was not the reason they supported Trump — that their hard choice was motivated by other, nobler causes."

My goodness.   Let's be apologists for wrongdoing, or as they would say, "sin."   Is this not the very definition of "temptation"? I get something I want, but it is attached to sin, to things I know are wrong?   This is how "Christians" have supported war, torture, genocide, slavery, witch hunts, etc., for the past 1700+ years, by thinking that way. 

The thing I see in conservative Christians is that they are actually just materialists.  They can rarely apply the living spiritual principles of Christ's words. In fact, they are so deficient at it, it's obvious that they do not really believe in those teachings for *themselves.*  Gerson avoids Christ's real teachings entirely in his open letter to evangelicals, when respect for those teachings would eliminate the need for this column altogether.
