Obama's "mischlinge"

Today's Ponder

I'm left wondering whether there was a  journalist in 1930's Germany who, worried about Nazism's incipient evil, investigated it's architects.  And, perhaps, discovered the butcher Reinhard Heydrich's Jewish roots.? Or,*gasp* that Hitler himself was mischlinge?  Maybe even tried to publish it.  I wonder what happened to him? Aside:  Ach, Mein Gott in Himmel! This reads more like a warning from the Obama campaign than the cheap sarcasm I intended.
