One can only imagine, but I suspect it wouldn't be nice. Incidentally, like most of us, while Sarah is no great beauty, she's not positively unattractive.
If she changed her mind about any part of support for Trump ... even acknowledged, “Hey, this is the opposite of what we said yesterday!” ... she would gain 50 lbs., lose 50 IQ points, and have always been a (fill in misogynistic invective). I recall this happening to Mike Huckabee, except for the misogynistic part.
I agree. Sarah Sanders is an okay-looking lady. In another situation - playing with kittens, perhaps - a happy expression would make her more attractive overall.
