I only noticed one serious issue with Holt. Debate moderators should not be acting like fact checkers. Hillary claimed Trump was for the Iraq invasion. Trump said, “No!” That’s when Lester Holt stuck his nose in it and claimed Trump did support the invasion which put Trump on defense.
The moderator should let the candidate’s statements stand. They can be rehashed after the debate, but taking sides like that actually harmed the overall debate by forcing Trump to waste OUR time to respond in more detail to Lolt’s (and Hillary’s) claims. Holt should have kept his mouth shut other than to ask questions and control the amount of time for each candidate.
I actually thought the exchange between Holt and Trump on Trump’s supposed support for the Iraq war was helpful to Trump. It gave him a chance to air it out and explain himself. The left has been portraying his comments on the Howard Stern show as some kind of definitive position statement on Iraq. But that’s BS, and he got to explain why it’s BS, and he did a good job of explaining it.
