Trump has all the momentum and he is now running a tight and disciplined campaign so I don't expect any further ammo coming out from his unscripted jokes being twisted by the media. Where he's ahead, he'll stay ahead. Where it's tight, independents should be watching this Hillary drama and rolling over to Trump and he can get close the deal with them. That alone might be enough to win it.
But is it so bad with Hillary that he can flip places that have a big Hillary advantage? If he does, it's a landslide.
