It can be be Merl Haggard for all i care, since the president's job is to
1) Fill up an appointment in the Istana
2) Wave to the public and preside over an annual show on the 9th of August every year
3) Defer to the cabinet on the decisions that he can (or have to) make
4) Collect a nice fat salary
so in short, since whoever is the president is nothing more than a powerless figurehead, its just a question of whoever is favoured to enjoy the perks
