There does seem to be some great dissension in the Trump campaign over this matter. It was sounding like his campaign manager was wanting him to soften up his stance to spread his appeal beyond his base, but then Trump decided to ignore her and double down on what he was saying in the primary. I guess all the talk about him flip-flopping on his position made him angry and he randomly decided in a huff to scrap the entire plan.
There's two problems. First, Trumpy doesn't make decisions, he just shoots from the hip because it feels good. Secondly, if he alienates his extremist nutter core constituency, which is what won the primary for him, he's a fucked duck.
So maybe if he's decided anything maybe it's just to rearrange chairs on the Titanic and enjoy the ride.
