Neither Ishii or McCartney will be able to save Ige.  Ige's only hope is that no one from his party decides to throw their hat in the ring.  Otherwise, their will not be any real challenge for him to get in for a second term as we are a one party
banana republic, uh I mean state.  However whether it is Ige or another of the party faithful, it is not going to  make a difference.
