If people think racism is dead, read local newspapers throughout the deep south, oklahoma, Tulsa, in particular. Racism is alive and well. The KKK is alive and well. Just read some of their comments to articles about obama. I live in LA so that when i read those comments, it is downright scary. It 's not the KKK or white supremicist groups that are at fault but the Southern Christian Poverty Law Center. It's unbelievable.
Those whites feel that they have been marginalized now (and they are correct). They are downright scared. They have a simple agenda - fear, which is based upon ignorance and intolerance.
Demographically, if you look at those who voted for obama, it's those with higher education. Do a breakdown on Politico or REal Clear Politics and you can see for yourself.
