Presidential historian Brinkley: If evangelicals flee Trump over alleged porn star affairs he's doomed

Appearing on CNN's New Day, noted presidential historian Douglas Brinkley claimed that President Donald Trump's base is predominately made up of evangelicals at this point and, should there more revelations about him having affairs with adult actresses, they may grow fed up and flee dooming any chances he has of reelection in 2020.

Speaking with host Victor Blackwell, Brinkley said he was amazed at the number of evangelicals who have stuck it it out with Trump considering his history with women, his Access Hollywood comments and his multiple marriages.

Noting a Trump-backing pastor defending Trump over his alleged affair with porn star Stormy Daniels, Brinkley called the response "disappointing."

"You would think that they would hold everybody to an equal standard, but the rules don't apply to Donald Trump," he explained. "They've decided that he is their guy. They don't care that he was a casino magnet, they don't care about the Access Hollywood tape, they don't care about the women that are charging him for sexual harassment. They don't care about him being with a porn star."

"It's like he has an inoculation," Brinkley continued. "If they would start turning on Donald Trump, you would see his base shrink. Donald Trump is holding at about 35 percent.  If evangelicals would start saying, 'We've had enough of this immoral president,' you would see Trump's base start shrinking and possibly the end of getting reelected."
