I think the bigger news is the gradual rise of Rubio and Cruz. I still think that when the field gets weeded down to the top four that most of the other, lower tier candidate support will not go to Trump. But hey, I could be wrong. I do not understand what the end game is for Bush, Fiorina, Kasich, et al. They have no hope in getting the nomination.
I would point out one aspect of your post that is wrong. There was no massaging of intelligence during the Bush administration as determined by a bipartisan commission specifically focused on that issue. They were unequivocal about that point. And further, as we have belatedly learned, Iraq did have WMD...unless you subscribe to the latest fantasy that WMD somehow only means nuclear weapons. Only really ideologically blind people still tell that lie.
