You know it was the Democrats who measured how much "Black" one had in their family line during the days of Jim Crow. SO it doesn't surprise me they continue to do this even when it's 50/50 black/ white.
I doubt if her dad was 100% black---kindof like Tiger Woods---he is more Asian than Black--he even looks more Asian but he is considered Black.
I was invited to sit on a few 'diversity' roundtables in my day. I can tell you that democrat liberals are the most obsessed racial beancounters you'll ever come across.
