Never gonna happen.
Sez you.
If charges are filed against Obama, there will be riots like we have not seen before (Picture the OWS riots times ten).
To prevent this the GOP will cave and scape goats will be sacrificed. Susan Rice comes to mind.
Obama will proclaim his innocence: "witch Hunt", "racist", "Putin ordered this" etc.
Much as I would like to see it, it will not happen.
