Evangelicals catapulted George W. Bush back to the White House.
How do the same evangelicals who incessantly force-feed us their morals and family values manage to overwhelmingly support someone like Donald Trump?
Why do evangelicals support Trump? It could be because he amplified his religious messaging on the campaign trail by saying that women who get abortions should be punished and that he's not in favor of same sex marriage.
Trump has benefitted indirectly from a strong belief of evangelicals that the two terms of Barack Obama has led the country to the brink of destruction. Obama was bad enough in their eyes; having the Clintons back in the White House would be the end.
Voting for Trump will either hasten the return of Jesus, according to evangelical belief, or to allow evangelicals to regain political power in the White House. Either way, it is a win-win situation.
Trump, despite his divorces and 'worldly lifestyle', appeals to evangelicals because he is wealthy, powerful, and pays them lip service. They support him because they are tired of losing the culture wars and are addicted to the perks of power.
In the past, candidates' performances of 'Christianity' have been strong points for voters, but Trump's ascendancy with evangelicals has eviscerated that expectation. Evangelicals, like other voters, can be very pragmatic about the issues they want addressed by the leadership they support.
Trump, despite his shallow depth of biblical knowledge, plays into both the apocalyptic end-time fears of evangelicals and their nostalgia for a 'small town' America.
Trump's blatant racism and demonization of Muslims, Mexicans, and immigrants also serves as a foil for white evangelicals. By othering these groups, Trump allows evangelicals to persist in their belief that white Anglo-saxon Protestantism is the default for true American Christianity and is best suited to lead America as a 'Christian Nation.'
McCain courted in 2008 what I would call 'fringe' evangelicals, in part because evangelicals were skeptical of his commitment to values voters. McCain's embrace of Palin came after having to scuttle endorsements from John Hagee and Rod Parsley, charismatics who believed in Armageddon and fiercely supported Israel.
