re: #89 Quoth the raven, Covfefe.

They bother because putting on the appearance of holiness is important to their electability. If they stopped trying to look like Christians on the outside, eventually the evangelicals would catch on (notice I said eventually), and their power base would evaporate.

Given the evangelicals accepted an adulterer thrice married as their savior - I doubt they will EVER leave the current version of the republican party. Only thing that might force them away would be if the GOP nominated a black man for President.
