If obama’s election is voided( a law requires,not impeached) It would void all electorial college votes for obama. this would leave McCain with the majority of the votes and the legal president of the U.S. If obama’s election is voided,it’s voids everything he during and after his election is voided ,this includes the selection of biden as vice-president. obama did not have the right to select a vice- president if he never had the right to be president.
