How Trump out did Bush and Romney with white evangelicals.

In 2004, white evangelicals were 23 percent of the electorate, and they cast 78 percent of their vote for fellow evangelical George W. Bush. In 2012, they were 26 percent of the electorate, and gave Mormon Mitt Romney 78 percent of the vote. In 2016, Donald J. Trump, a thrice-married man who bragged about sleeping with married women and whose biblical knowledge at times seemed confined to the foibles of the two Corinthians, won 81 percent of their vote. Notwithstanding the fact that I have been assured repeatedly that these voters represent a shrinking demographic and that Republicans had maxed out their vote share among them, they were once again 26 percent of the electorate. ...
Second, you may wonder why this group voted in historic numbers for a man like Trump. Perhaps, as some have suggested, they are hypocrites. Perhaps they are merely partisans. But I will make a further suggestion: They are scared.
Consider that over the course of the past few years, Democrats and liberals have: booed the inclusion of God in their platform at the 2012 convention (this is disputed, but it is the perception); endorsed a regulation that would allow transgendered students to use the bathroom and locker room corresponding to their identity; attempted to force small businesses to cover drugs they believe induce abortions; attempted to force nuns to provide contraceptive coverage; forced Brendan Eich to step down as chief executive officer of Mozilla due to his opposition to marriage equality; fined a small Christian bakery over $140,000 for refusing to bake a cake for a same-sex wedding; vigorously opposed a law in Indiana that would provide protections against similar regulations – despite having overwhelmingly supported similar laws when they protected Native American religious rights – and then scoured the Indiana countryside trying to find a business that would be affected by the law before settling upon a small pizza place in the middle of nowhere and harassing the owners. In 2015, the United States solicitor general suggested that churches might lose their tax exempt status if they refused to perform same-sex marriages. In 2016, the Democratic nominee endorsed repealing the Hyde Amendment, thereby endorsing federal funding for elective abortions.
