Kennedy told supporters that she believes Obama represents a vision of opportunity, fairness and a better future, while the "Republican vision, like Richard Nixon, would turn the clock back on so much of the social justice and economic problems."

She said she believes Obama exemplifies the qualities of leadership her father wrote about in "Profiles of Courage," including "the courage to keep fighting for all Americans, no matter what special interests or personal attacks are used against them."

One of Obama's early supporters in his first presidential campaign, Kennedy endorsed the then-U.S. senator as a Democratic candidate in a January 2008 New York Times op-ed piece.

Titled "A President Like My Father," Kennedy wrote that she believes Obama inspires people of all ages with a "sense of possibility."

She was later appointed to lead Obama's vice presidential search committee.

"I really believe Barack Obama is fighting for the America that I believe in," Kennedy said, urging New Hampshire Democrats to make sure they are registered and ready to vote come November.

Karl Stamm, a registered Republican who traveled from Hudson to hear Kennedy speak, said he is also inspired by Obama.
