Doesn't surprise me. I'd be more interested in the 7% of Germans that support Romney. Who is that? I doubt anyone I know here is against Obama. NPD voters and xenophobics?
The two people I know who support the NPD are the same two [German] people I know who support Romney.
It actually surprises me that NPD voters would support Mitt Romney. After all he's a "Zionist puppet" and candidate of the "Jewish-American corporate elite".
Germany has a very tiny group of neo-conservatives who are staunchly pro-American (read pro-Republican) and pro-Israel (read pro-Likud), who supported the Iraq invasion in 2003 and would support an Israeli strike against Iran. Think Henryk M. Broder as an prominent example (ignore his religion please, there are also non-Jewish examples). I suppose most Romney supporters must come from that group.
