How is that racists? Is it sexist that most women gravitate towards Clinton because she's a woman (including that 11% of blacks voting for her who are mostly black women)? Is it right? No. But white men are undefeated in presidential elections here, finally there is not only a candidate for significant, real change but also someone who can relate to our collective 'struggle'. Its the same way Mormons came out in force for Romney, evangelicals for Huckabee. Its all about similar indentifying principles and characteristics. Its just human nature.
