Clearly, a political chasm divides the white evangelicals from the non-white but especially the African-American evangelicals. But why is the R-G so eager to pat the backs of the few white evangelicals who have dumped Trump? After all, they did so only AFTER the Billy Bush recording and only because it exposed them as the disgusting hypocrites they are. This minority of white evangelicals still supports the other decidedly unchristian values espoused by the Republican party and have done so for decades. 
So there's a growing "sense" that character matters among evangelicals--big deal, it only matters to an certain extent because the nature of the political system is much more determinative than a particular candidate's character. 
The policies and ideas espoused by Republicans are as repugnant as their candidate is and have been so for a long, long time. Trump represents the Republican party very well. Embrace your spawn, Republicans, and have the dignity to go down with the ship.
