Don't get me wrong, if it does all burn down overnight I'll gladly bring the marshmallows. I'm just cynical enough that I won't be holding my breath. The GOP has further depths they can stoop to before they hit rock bottom.
Oh I am not holding my breath, but I also think that Trump's position is more precarious than it might seem.
The facade is strong, and his base might still be deluded but I'm sure that his important political allies are only calculating whether it is better for them to support or flip. If a couple decide to flip, then suddenly the arithmetic changes for the rest and they'd probably also flip - after all, being faithful to a liability is not good for one's political welfare.
