That's actually funny. White. Evangelical. Christians. Where's the emphasis in this label? White, evangelical, or Christian? "Progressives" tend to think all three are bad. Yeah, that's really going to get "Progressives" the "Whites," "evangelicals," and Christian votes.
Somehow I don't think "White Evangelical Christians" are the only ones who're hoping to eventually go to Heaven, or reach Nirvana, or whatever you want to think comes later. I really don't. Atheists, who look forward to a dreamless sleep of non-existence, are excepted. And no, that's not a slur. Isaac Asimov said as much in an essay. And yet when we have a public figure express the same thing most are hoping for, in the exact same way, by "good works," then it's immediately labeled as appealing to an imaginary "voting block," even though Christians immediately pick up on how it's trusting in one's own works and not Christ.
Taken at face value, Trump's statement is no different than an average American saying "I'm a good person. I hope I make it to Heaven." None.
