Kathleen Willey would be the better choice.
Except that Gennifer Flowers has the personality to take on the MSM when things get hot. From what I recall of each, Flowers will be a lot more effective in interviews that may follow....
But I agree that highlighting Bill’s assaults and Hillary’s cover-ups may be more important than Flowers who was (so far as I know) a consensual paramour. Still, Shrillary did help Bill cover-up the Flowers affair when it burst into the campaign news in 1992, so it is not irrelevant to tweak Shrillary on her decades-long campaign of lying and trying to discredit the many women in Bill’s life.
