This comes from an opinion piece in The Wall Street Journal:
It’s also worth noting that in the vast digital trove of Mr. Podesta’s stolen emails we haven’t noticed emails from Mrs. Clinton. Perhaps they don’t exist. But American voters shouldn’t worry merely about the emails released before the election. What emails or memos exist that these hackers, Russian or not, could be withholding for leverage after the election with another President Clinton?
Good question. Something tells me we’ll find out the answer soon enough.
