It is no mystery that Protestant Christians vote for the Republican ticket by a huge percentage, be it Trump, Romney, McCain or whoever. But in regards to the death of Christianity claim, the writer is either not paying attention, he's an idiot, or he's a Secularist zealot. My guess all three. Secularist have been trying to prove their case for the death of Christianity since at least 1966 when TIME Magazine had on their cover just these words, "Is God Dead?". No He's not, He is alive and well. Even in this day and age some 80 percent of Americans still identify with being Christian of one denomination or another, so the public rightly sees America as a Christian nation still.
Do we need any more proof the Christianity still thrives than looking no further than the movie box-office. Faith based movies are a huge success and very profitable. The 2015 hit "War Room" cost just $3 million to make but grossed $67.8 million in box-office receipts, and the entertainment industry is taking notice. More and more producers and executives are trying to tap into the market for belief-affirming movies.
Some of the Christian Faith-base popular movies as of late.
God's Not Dead 1 & 2
Fireproof
Miracles From Heaven
Risen
The War Room
Mom's Night Out
Heaven is For Real
Unstoppable
Unbroken
If Christianity is dead, and American is now a secular nation, these movies should have been flops.
