I’ll concede that she didn’t inform Kristol.
Allow me to ask this: If Sarah wanted to ‘reveal’ this to the Media (public), wanted to do it ‘personally’, and picked the time to do it, wouldn’t revealing it to anyone else (especially a member of the MSM), be very counterproductive?
I’m pretty sure Bill Kristol can keep a secret. He’d have no reason to leak and probably would have had a stronger defense for her.
