To quote the man's favorite President: "You can fool all of the people some of the time."
When it comes to Evangelicals, I think you meant "you can fool some of the people all of the time".
Also true, but not the angle I was going for.
Trump is an inveterate and notably inconsistent liar. If you're in the mood to be "persuaded" by him, you can look through his statements and cherry-pick your way to convincing yourself that he's entirely in agreement with you. Evangelicals see his occasional hard line on abortion (we'll need to have penalties for people who get abortions, promises to appoint hardline judges to the court), while Midwesterners and folks from New Jersey like that he's not a Southerner and clearly isn't a crazy holy roller.
You can have it both ways when campaigning; somehow the man pulled off an amazing feat of simultaneously getting a majority of college-educated whites to still support him (thinking that he's a regular Republican) while getting an overwhelming majority of non-college-educated whites to back him on the premise that he's the champion of the common man.
You can't really have it both ways when governing, though I'm sure he'll try to. Sooner or later, he'll have to piss off some part of the 46% of the country that voted for him---though he could get a long way by just acting like a normal Republican with enough Carrier-style sleight of hand and race-baiting to keep the Trumpenproletariat on his side.
Thankfully, he's not that competent. He does actually have some governing to do, and you can't do that by being a media personality.
