I think the operatives are bringing this up in hopes that it will show Hillary to be the anti black racist she has apparently been. But even if she had proof this was an offspring of Bill, LOTS OF PEOPLE PUSH AWAY A SURPRISE ILLEGITIMATE CHILD, even of the same race.
This doesn’t seem like a winnable thing, if it is a thing at all. I believe the bill sterile thing.
If I ever run, I might make “Pity for bastards, it’s not their fault” a campaign theme. That could win me a chuck of the democrat base.
