DAVID BROOKS: Usually in this stage, if you’ve won as much as Hillary Clinton and Donald Trump have won, then everyone is rallying around you, you’re relaxed, you’re happy, you’re cruising. That’s not happening this time mostly because they have significant weaknesses. With Hillary Clinton it’s still the basic trust issue, the party is still a chunk to her left.

To me the big story this week is whether something with Donald Trump has shifted. Now of course we’ve been saying it for eight months, finally he’s done it this time. But I do think — and I’m still a little dubious about the people who think something has shifted. But there’s a more plausible argument that air is coming out of the balloon for him. And I think that’s because given what all he’s won and given what everybody including his wife is apparently telling him, be more presidential, he can’t control himself. He can’t control himself temperamentally with the aggressive attacks on everybody. He can’t control his own ignorance which causes the abortion statements.
