From the Boston Globe:
Kerry takes another look at presidency:
Says loss in 2004 made him tougher

"When you get knocked on your ass and lose a race, you’ve got to stop and reflect on what you’re doing, why you’re doing it, what matters, and what’s important. And I did," Kerry said in an interview in his Senate office on Thursday. "There’s a very different John Kerry now who is absolutely crystal clear about how I communicate what I need to communicate. . . . People are going to be looking for leadership."
