There are lots of good Democratic candidates, but when you run most of their proposals through the sausage factory, not much differentiation.
Barack offers something different in a big way, though, in a way where I'm quoted by Jose Antonio Vargas in the Washington Post
"I figure we really need a guy who knows right from wrong," Newmark told The Trail, "and who can remind the world that we're the good guys."
I'm not an American "exceptionalist"; I'm a customer service rep, and have spoken with thousands of people in the US and overseas. Everyone wants Americans to be the good guys again. We need someone who can credibly remind and lead us back into good guy-ness, in terms of of our actions and how we're perceived everywhere.
Leadership means that you need to be able to bring out the best in people.
Barack's the guy to do that.
