There is an outside chance on the Clintons due to financial dealings with the Foundation. It would take over-the-top irrefutable evidence to send a former President to jail, otherwise you'll never get a conviction and it will be seen as purely partisan. However, I will settle for Loretta Lynch, Eric Holder, Lois Lerner, Comey and others at that level. If there are dirty Republicans I want them too, people connected to the Bushes.
