Why are there articles saying "white voters played key role in clinton's KY victory? double standard?

don't tell me that if there were articles saying "black voters played key role in obama's NC primary victory," there would be writers losing their jobs. just like the clinton advisor who lost her job when she said that obama is getting most of the black vote simply because he is black. (he was getting close to 90% of the black vote... tell me that is based on issues). the double standard in the country is sickening me and i feel discriminated against as a white. not to mention the incredibly outdated affirmative action. is this ever going to change?
