First things first: Trump meant to type “coverage” — it’s pretty clear based on the context of the rest of the sentence. The reason Twitter lit up for more than 24 hours was not because people genuinely didn’t understand what Trump was trying to say; rather, they were ridiculing him for:
1) Making the typo;
2) Actually tweeting the typo, and;
3) Leaving the typo up for more than an hour.
It was dumb, and Trump was roundly mocked for it, but honestly, in the grand scheme of things, this doesn’t even rate in the top 100 dumbest things Trump has done in…hell, in the past year alone. You would think this would be obvious to any observer, regardless of their political leanings. And in a normal universe, Trump supporters would laugh it off and go on with their lives, and the internet – as it always does – would eventually move on.
