If Obama pardons Clinton before inauguration to prevent her from being impeached, we will have a serious crisis. I hope it won't degenerate into violence, but there will be a lot of very angry people -- an a powderkeg ready to blow at any time.
A more likely scenario is a bloc of states begin the process of secession, daring Clinton to start another war between the states.
She might even do it.
In order for Obama to pardon her, wouldn’t she need to be convicted first? As far as I know she hasn’t even been charged with anything yet.
