While his parents seem like major league evil assholes, from initial research scan on Mezvinsky the younger, the guy sounds like a useless putz.
Not successful, and has managed to lose assets of wealthy Clinton supporters.
Tried to pull funds from CF to save his failing company.
Sort of an Anthony Weiner type in terms of liability to the Clintons. He could be a real weak link in any crime network.
Could it be, Marc Mezvinsky is /ourguy?
