Do you remember “50 First Dates”? It was a Drew Barrymore movie about a woman with short-term amnesia who wakes up every morning with no memory whatsoever of the year that went before.

I am thinking it’s the perfect Donald Trump analogy.

In the past, I’ve always presumed that when Trump completely changed his position on health care or the Mexican wall or nuclear weapons in Japan, it was due to craven political opportunism. But it’s much more calming to work under the assumption that he doesn’t remember anything that happened before this morning.

Think about it next time you hear him bragging about his big margin of victory. “We won in a landslide. That was a landslide,” he told a crowd in Ohio on Thursday. It was perhaps the first time in history that a candidate used those terms after receiving 2.5 million votes fewer than his competitor.

It’s stupendously irritating, unless you work under the assumption that he no longer recalls the real story.
