I would not be running for president if I didn ´ t believe with all my heart that this is what the vast majority of Americans want for this country . This union may never be perfect , but generation after generation has shown that it can always be perfected . And today , whenever I find myself feeling doubtful or cynical about this possibility , what gives me the most hope is the next generation - the young people whose attitudes and beliefs and openness to change have already made history in this election .
