I don’t watch Fox News, but do see ads for her show and have over time. For me, the new look is a major turnoff. In some respects it makes her look masculine; a bull dyke. In another way, it makes her look sinister; someone who should not be trusted. Either way you look at it, the look is going to hurt her ratings IMO.
Would also add, I will be surprised if her contract is renewed, let alone be the rainmaker I am sure she was looking for. She is going to need to grow her hair back out, become feminine again and rebuild her brand.
The bull-dyke look was probably just to make her look like she has a brain instead of just being a toy for rich older men (after a close-up someone posted a few weeks back, I don’t think young men would be interested; she looked “worn”).
