Dr. Drang:

For weeks — maybe months, time has been hard to judge this past year — Trump has been telling us that he’s worked out deals with pharmaceutical companies to lower their prices by several hundred percent. Commentators and comedians have pointed out that you can’t reduce prices more than 100% and pretty much left it at that, suggesting that Trump’s impossible numbers are due to ignorance.

Don’t get me wrong. Trump’s ignorance is nearly limitless — but only nearly. I’ve always thought that he knew the right way to calculate a price drop; he did it the wrong way so he could quote a bigger number. And that came out in yesterday’s speech.

Trump sophistry + math pedantry = Daring Fireball catnip.
