Kennedy, who was four days shy of her 6th birthday when her father was assassinated, wrote that Obama "has a special ability to get us to believe in ourselves, to tie that belief to our highest ideals and imagine that together we can do great things."
And she appealed to other parents to pick a candidate who she said could invigorate a younger generation that is too often "hopeless, defeated and disengaged."
Kennedy wrote that she wants a president "who appeals to the hopes of those who still believe in the American Dream, and those around the world who still believe in the American ideal; and who can lift our spirits, and make us believe again that our country needs every one of us to get involved."
