Will no longer be watching Nora O'Donnell on the world news. She makes every report sounds like a crisis with her tone, including those reports that have a positive story. It is no surprise she has the lowest ratings. Perhaps she is trying too hard because her ratings are so low. You would do your network a favor to replace her.
I will be watching David Muir on another network. He moderates his voice and tone as he is reporting the (same) news. It's no wonder he has the highest ratings.
