As a former Hillary supporter, my first thought when I saw Joe Biden up there with Obama was, "Darn... There's no more girls up there." I love seeing a woman in the fray. But this is indeed an unusual pick.
Like it or not, John McCain, this is your case: Obama, you said the race is about presidential temperament. Well, eat this, Barack. You want to see my presidential temperament in action? Sarah f*in' Palin, man. That's the ticket!
