Most of us would prefer to base our voting decision on policy differences. However, the candidates’ goals are similar. They have all laid out detailed plans on everything from strengthening our middle class to investing in early childhood education. So qualities of leadership, character and judgment play a larger role than usual.

Senator Obama has demonstrated these qualities throughout his more than two decades of public service, not just in the United States Senate but in Illinois, where he helped turn around struggling communities, taught constitutional law and was an elected state official for eight years. And Senator Obama is showing the same qualities today. He has built a movement that is changing the face of politics in this country, and he has demonstrated a special gift for inspiring young people  known for a willingness to volunteer, but an aversion to politics  to become engaged in the political process.

I have spent the past five years working in the New York City public schools and have three teenage children of my own. There is a generation coming of age that is hopeful, hard-working, innovative and imaginative. But too many of them are also hopeless, defeated and disengaged. As parents, we have a responsibility to help our children to believe in themselves and in their power to shape their future. Senator Obama is inspiring my children, my parents’ grandchildren, with that sense of possibility.

Senator Obama is running a dignified and honest campaign. He has spoken eloquently about the role of faith in his life, and opened a window into his character in two compelling books. And when it comes to judgment, Barack Obama made the right call on the most important issue of our time by opposing the war in Iraq from the beginning.

I want a president who understands that his responsibility is to articulate a vision and encourage others to achieve it; who holds himself, and those around him, to the highest ethical standards; 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.
