Just to be clear, no one actually thinks that it took 6 months to come up with "Ultra MAGA", right?

Of course it didn't, Biden just took a word used to describe Trump supporters, and put ultra in front of it, I've seen that done so many times in the past: "Ultra-Christian, ultra-Nationalist, ultra-Zionist, and ultra-Leftist". I don't care where that claim came from, I haven't really looked into it, so either it's an assumption gather from a few loosely related facts, or entirely fictional, and it doesn't matter whether the lie came from some guy on the internet or the white house it's self, it's not true either way. I really wouldn't be surprised if it did come from the white house, Biden is probably laughing at all the Trump people showing how foolish they are.
