Hamas is quite popular in the Palestinian Authority. As are the PFLP and PIJ. Presuming elections are held one day, the terror groups will win. No elections, as you say he's not going to live forever and it's unlikely he'll have a peace minded successor. Personally I'd forget about him and try to establish a moderate government in Gaza, no small task. Let Gaza be it's own state and see how it goes.
