Evangelicals don’t like cheating spouses.
You mean like Trump ?
The vast hard working middle class could not give rat’s rear end about Mark Sanford’s cheating on his wife. That is not what is hurting the middle class. The big problem is the cheap labor express of H1B visa workers, illegal immigrants, and one million legal immigrants every year.
The middle class is hurting and very angry at career politicians such as Bush, Rubio & Cruz. Because Trump has opened their eyes, by exposing how ultra-rich donors control the career politicians.
That is why Trump won in NH & SC and may have won Iowa if cheating and fraud was not committed in Iowa. When a bible thumper attempts to cheat Carson out of his votes, people understand that.
