Barack Obama has been declared the Democratic nominee now by CNN, NBC News, ABC News and AP; his victory speech has already gone online. The historic occasion of a black Democratic candidate touched the hearts of even the grizzled veteran news anchors at NBC. Chris Matthews read comments from South African anti-apartheid icon Desmond Tutu, who recently said of Obama, "Where else in the world would you ever have had anything like that?" Fellow anchors Keith Olbermann and Tom Brokaw both sounded even more sentimental, getting a bit choked up talking about Obama in the clip after the jump. Aww. Sometimes your quavering voice makes a "Special Comment" all its own, Keith.
