The number of emails is irrelevant, you’re right. What matters is that she destroyed an email which proves she sold influence to a foreigner as Sec. of State. I know it.
HOW I know it doesn’t matter any more than the identity of Harry Reid’s imaginary friend who told him that Romney hadn’t filed his taxes. In fact it matters even less - because no future event can prove me wrong.
Even if she were to recover and release all those emails, she couldn’t PROVE that there wasn’t one more . . .
