No, Jamaican can be black. As for multiethnicity and blackness, she's also Indian. There is a gray area, but she still wouldn't be the first black female to make it as VP should she be elected. It's like Obama - he has a white mom, so it's just as valid to say he was a white president as it is to say he was a black one. If Barack's brother Malik were to be elected (obviously impossible due to national origin), he would be a black president because both parents are of black or African descent. If I (black/Hispanic) were to get elected, people could say I'm the first Hispanic, but such isn't the case, since I'm also black. We've never had a black president, and Democrats have had opportunities to present a black presidential candidate and failed.
