While eschewing emotion - and its companion, vulnerability - Obama should be careful not to sacrifice empathy, the 'I feel your pain' connection that sustained Clinton. This connection is the shorthand people use to measure their leaders' intentions. If people believe you're on their side, they will trust your decisions.
No doubt, the White House thinks the American people know Obama's story. But since the Inauguration, we've seen only the president's present: his perfect family, his Ivy League elegance, his effortless mastery of complex issues. We never see him sweat. And we forget that he ever had to struggle.
When I joined Bill Clinton's start-up presidential campaign in 1991, I was confident that women would play an ever more important role, but I never gave a minute's thought to what would happen if we won. When we did - and I became the first woman to serve as White House press secretary - it changed my life. But it didn't change the world.
