Actually, Kamala Harris is your next President. You just don't know it yet.
Well, in the way Barack Obama was your president. Meaning, she'll show up to read the prompter and answer to the blackberry.
She just doesn't seem as physically lazy as he is, so that part will be interesting. Much easier to keep someone out of the details who sleeps in until 10 and likes to partake in days long extracurricular activities of the Larry S variety.
