I'm torn as I think giving it at the White House would be equally powerful, as it would remind all his enemies that he's still there, still in the White House.
But I do think giving the speach would be super epic, it would be off the charts to have it there, considering its history.
Compare either location with that senile prick Biden. giving his acceptance speach from his basement.
How funny would it be, if he went up to podium dressed up as Lincoln with a top hat and fake beard then took it off. The left would lose thier minds.
I think he will have at Gettysburg. He is not just President, he is firstly a showman, I would argue the greatest of all time.
