If Bernie had gone negative

[Fight for Trump]

If Sanders had gone after over the emails back in the fall, then he might have moved the needle and could very well be the nominee.
Still, I think the only person who could have beaten Hillary this year was Warren.

Yes, peddling Republican talking points/witch hunts would surely play well in a Democratic primary.

Again, the emails are not a right-wing smear. It's very different from Benghazi.
