I don’t understand this argument. Have you ever been to Cleveland or Philly? I am not at all surprised that Romney received no votes in large parts of both cities. This is about voter choices, not statistics. There are areas of both cities where a few republican voters live (parts of South Philly for instance are still somewhat GOP friendly). But huge swaths have no republicans at all - zip, zilch, nada.
These people are also largely idiots. Not even one mistake?
And they managed to get 90%+ turnout?
And this just happens to be in precincts where they expelled the Republican poll watchers?
Smells bad to me.
