In front of tens of thousands of cheering supporters, Barack Obama gave his acceptance speech one hour after it became clear he would be the next President of the United States of America. President-elect Barack Obama told cheering supporters on Tuesday "change has come to America" and called on Americans to back a spirit of unity to attack the country's pressing challenges. Obama congratulated defeated Republican John McCain for the long, hard campaign that he fought. He called on Americans to support a "new spirit of sacrifice." Obama stated; “I just received an extraordinarily gracious call from Senator McCain. He fought long and hard in this campaign, and he's fought even longer and harder for the country he loves. He has endured sacrifices for America that most of us cannot begin to imagine, and we are better off for the service rendered by this brave and selfless leader. I congratulate him and Governor Palin for all they have achieved, and I look forward to working with them to renew this nation's promise in the months ahead.” "The road ahead will be long. Our climb will be steep. We may not get there in one year or even one term, but America, I have never been more hopeful than I am tonight that we will get there," he said.
