That's what the Daily Mail is rumoring. Unless there is a revelation of some significant misbehavior, this isn't big at all. It mainly makes Trump look small. And it's not helpful to Romney's cause for Trump to claim the spotlight, in the last 2 weeks of the campaign, over this.
Who cares about the internal workings of a political marriage? I always assume there's some phony PR to it. But the fact is they are together, they've played the public role of married couple, and they have 2 very real little girls who don't deserve to be hurt. And because of that, Trump's news, if this is what it is, will only make moderate, middle-of-the road voters feel compassion for Obama.
Trump should crawl back into his hole right now, before he does any damage.
