Actually, there's a tendency for higher educated people to have weaker prejudices, maybe it's simply more cultured, but there's a general benefit if people react less upon thier prejudices and try more to keep it fair.
To be fair, that's 1/64 Afro-American blood, although an interesting curiosa story (that I didn't know about), but circus director to prime minister in a few generations is quite impressive.
Except when it comes to religion, that's one of those odd thingies you don't get from a European perspective. Here (atleast in northern Europe) if you're Christian or whatever fine no problem, but you don't talk about it. If you seek guidance from God, Jesus, Allah, Kali, the Flying Spagetti monster, three midgets or whatever you don't talk about it. Simply put, it's a private matter. Sure it might affect your politics, but then we see it there and not when you proclaim your faith.
To put it differently, I don't know the (lack of?) religious faith of our PM or any other minister or party leader, even if I can guess in some cases (like that the leader of the Christian democrats are probably Christian and the leader of the Left party is probably atheist).
