I've let the Kerry fact of the day idea slide, but here's a good overall point from the man himself in this AP article:
"I've heard some people say, well, what's the message? What's he doing? The message is clear, folks: We're going to make America stronger at home by being fiscally responsible, investing in health care and education, becoming energy independent, and we're going to make ourselves stronger in the world by restoring America's respect and influence with a better foreign policy. It's that simple."
Sounds good to me.
