The absolute worst case scenario would have her pardoned by the President.
You guys are really delusional.
This is what will happen should Hillary face any criminal charges. President Obama might not want to do it, but the Clinton's are good for business for the Democratic Party, and no one is bigger than the party when the rubber hits the road.

If they charged her today and Obama pardoned her tomorrow, I think she would still easily win the nomination.
