A PEW study conducted this year found 2/3 of evangelic republicans had a favorable impression of Donald Trump. For over a decade, people have been trying to understand why so many highly religious Americans have favorable view of Trump. He has been married 3 times and divorced twice, has admitted to adulterous relationships, been found liable for sexual abused, accused of rape and sexual molestation, paid hush money to porn stars and prostitutes, and is now convicted of felonies in New York. Yet he claims to be religious but doesn't have time to attend Church.
If you're not familiarly with Christianity in American this may seem perplexing. Many so called Christians divide their lives into their business life, family life, religious life, political life, etc. I believe these evangelic republican's political values take precedents over their religious values. I think the name Christians in name only applies.
However, keep in mind that 1/3 of evangelic republicans do not hold favorable views of Trump. It seems likely that they are true Christians whose Christian values extends to all parts of their lives including their choice in political candidates.
Among religious groups, White evangelical Protestants continue to have the most positive opinion of Trump.
