The only thing harder than delivering a concession speech must be writing one. But Hillary's speech is striking all the right notes, while still letting her hit her familiar campaign themes in a way that makes the speech sincere and authentic, without seeming to be forced. If you're not a Hillary fan, you'll probably think the speech was too much about her and not enough about Obama. But I didn't get the sense that it was a begrudging endorsement. Judged against other concession speeches, I think she did it just right. Your thoughts?
