I don't know if there is PROOF of anything impeachable with The Decider. But if there could be unfettered, exhaustive investigations -- I suspect he could probably be convicted of all kinds of crimes. Possibly treason, if betraying your country in service to your own and your Vice-President's personal financial interests could be considered treason.
Sorry. But he's scum. It's all I can do not to hate the man and just confine my hate and rage to his behavior and policies.
If he's convicted and tossed out.....do you want Richard B. Cheney, President of the United States? Didn't think so?
