Lady Gaga has been pretty vocal in her dissent of Trump, and she's about to perform at the super bowl!
When Gaga has her big moment tomorrow, it's almost inevitable for him to to tweet and try to insult her or her show.
So, what might he say?
I doubt he'll say anything unless she mentions him, which she won't. Although I expect she'll make some kind of statement, but in such a way that it goes over his head.
