Coulter is a lot of things…but dumb is not one of them. I doubt she says or post anything that she has not given careful thought to and how it will benefit her “brand”.
If you put food on your table by being controversial, combative and abrasive; then that’s what you will do. Someone who supposedly studies history (albeit through a biased lens) the way she seems to do knows H.W. Bush’s history as well as we do.
Making him the epitome of the “wimp”; and stating it unapologetically; keeps her relevant, or at least in the spotlight to sell books and get lucrative speaking engagements.
