My *Moment of Zen*

So I read the information about the Bradley effect and I just wondered if there would be something like the Özdemir effect if ever a Turk would run for federal chancellor in Germany?
And I´m strongly convinced that it would. It is because of the history of our country that most Germans are afraid to be perceived racist. I have to admit that I myself always think twice before saying something about foreigners - even if it is something positiv - just because I fear being misunderstood. Therefore I suppose that being asked in a poll which candidate they favour, the German or the Turkish one, many Germans wouldn´t answer honestly.
Thus, far more interesting would be the question how long it still takes the Germans to finally overcome this phenomenon and really cast their votes for a candidate with a foreign background? When will Germany have its own Barack Obama? And I found some humorous video trying to answer this question but also some serious discussions which mirror the overall attitude towards that topic...
