DONALD TRUMP: I don't believe the polls anymore. I don't believe them.

White evangelicals are reliable Republican voters. They also have a long history of demanding that politicians exemplify character and morality in public life.

So for many, Republican presidential nominee Donald Trump presents a moral dilemma.

Brent Harger of Washoe County, Nev., says he has always voted, but until this year, he'd never really gotten involved in politics.

Donald Trump has apologized for his vulgar comments about women that were revealed in a recording obtained by the Washington Post on Friday.
