No way will Obama ever resign, forced or otherwisw. The Dems would be committing political suicide with such a move. Deny, deny, deny works. Bill Clinton now has a personal popularity rating of over 70% despite being only the second President ever to be impeached.
If push comes to shove between Obama and Hillary...the Democrates and Congress will come down on Hillary’s side....so she’s being protected even moreso than the President.
