Why is this getting any news coverage?
Because its an "acceptable" way to be racist. Instead of saying its about a black (or hispanic, or asian, etc)President they want to make it appear like its a larger issue of how the country is split on policies.
Of course, its quite obvious to most Americans its just a way of saying we hate blacks so much we don't want to be a part of a country that elects one.
Its also a function of the lies the old Confederate states tell themselves and their children that the Civil War was over states rights. Even they know its b.s. It was all about the economics of an economy that was built on slaves and their unwillingness to free them.
No slavery, no Civil War.
