"I really don't even know what I meant, because that was a long time ago, and who knows what was in my head?" Trump said. (You can read the full back and forth here.)
Okay. Let's take a step back here. Trump is the clear favorite for the Republican presidential nomination. He has insisted that his lack of experience in elected office is a non-issue because he has demonstrated the good judgment that many of his political rivals have not. Point No. 1 of that argument has always been that he was the only Republican running for president who opposed the Iraq War from the start.
Except that he didn't. And, his explanation for that fact? 1.) It was a long time ago. 2.) And I quote: "Who knows what was in my head?"
Now, imagine any other presidential candidate in either party offering up that response to any question — much less one about the central foreign policy decision of the past two decades. That candidate would be filleted and roasted for his lack of knowledge. Doubts would be raised among his supporters about whether he was ready for the top job. The candidate would be compelled by his advisers to give a high-profile speech explaining the contradiction in positions and the remarkably flip initial answer he offered to explain away that contradiction.
For Trump, it's just another Sunday. There will be no big speech to explain anything. There won't even be a statement trying to clarify. The man most likely to be the Republican nominee this fall — and, therefore, to have a real chance at being the next president — will simply stand on his it-was-a-long-time-ago-and-anyway-I-just-say-stuff explanation for taking two absolutely contradictory positions.
That reality tells you everything you need to know about Trump and his position in this race. Normal rules of politics don't apply to him. Hell, rules of any sort don't seem to apply to him. His supporters seem uninterested or unbothered — or both — by the fact that something that Trump used as a proof point for his judgement has not only been proved wrong but also that his explanation is, basically
Any suggestion that Trump's acknowledgement that he just doesn't really remember what he said or meant about Iraq will slow his momentum in the Republican race is based on having spent the past eight months on another planet. It will not slow him. It will not stop him. It may, in fact, further convince those who are for him of his anti-political chops: What politician would ever admit they have no idea why they said what they said, after all?
Trump has created a bizarro world of politics. What looks like up is down. What looks bad is good. The rest of the field — and the media horde covering the candidates — needs to adjust to the fact that this is the new normal.
