Spent most of his childhood formative years in a foreign country (Indonesia / Austria). Hence, divided cultural allegiances and legal difficulties before establishing that he could hold office in his "adopted homeland." CHECK.
Was indoctrinated as a child in the State religion (Islam / Catholicism), but later abjured that religion (at least, in the public eye) while still trying to harness it for his political aims. True religious allegiance at best unclear. CHECK.
Had little or no relationship to his biological father ("Daddy Issues") and an ambiguous relationship with his weak / absent mother. CHECK.

Wrote an autobiography lamenting his tortured childhood, feelings of cultural / racial alienation, and ambivalence towards his host country. CHECK.
Initial support from the electorate based upon his racial make-up; nearly 100% support from that segment of the electorate with whom he identified racially. Had a political career marked by a tendency to incite racial animosities / foment divisiveness in his "new homeland." CHECK.
