Harry Enten is the CNN journalist who reports the polls. Since, I like polls I've seen him a few times in video clips of his segment. I've always found it really strange. He sort of shouts and waves his arms about each poll and makes some jokes about how "VERY BAD" or "Incredible!" or "no change" the poll is.

He sometimes explains important concepts such as "margin of error" but mostly turns numbers into adjectives.
