Seriously?
I think he is pretty independent and calls politians out when they are b.s.ing him. He was one of the few that took the Benghazi story forward.
I think his weakness is doing election night coverage. While he is usually right, he has an awful way of delivering the news during those live events. I also don't think he is very good at this live presidential debates. But, all in all, he delivers a pretty good show nightly in a fairly independent way.
I would not classify Brett as a lib, but he is most definitely a “Swamp Guardian,” which I find almost as loathsome.
