The practicality of unseating a president in office remains to be seen. This is the first time EVER that an indictment has been handed down on a sitting president; it will in effect be little more than a formality if the UN does not agree to go in and remove him. I think that if elected, Obama will have bigger fish to fry, and it will fall on the UN and the AU to carry out the arrest, and the role of the US will be fairly minor.
