The trouble with fact checkers was quite evident in the Trump-Harris debate.
That could lead to a debate between the fact checkers, which would derail the debate.
Better to not have fact checkers as part of the debate, and leave the fact checking to the post-debate analysis.
Were they fact-checking too much? Not enough? Incorrectly?
Oh wait, fact checkers don't work, better just inform yourself and make up your own mind, and don't just believe some supposedly authoritarian figures.
