Kennedy, flanked by his wife Victoria Reggie, left, and niece Caroline Kennedy Schlossberg, is greeted with applause and tears as he makes his way onstage at the Democratic National Convention at the Pepsi Center in Denver in August 2008. “So, with Barack Obama, and for you and for me, our country will be committed to his cause. The work begins anew. The hope rises again. And the dream lives on,” Kennedy said in his address, echoing his words from the 1980 convention. (Robyn Beck /AFP/Getty Images)
