This is what I wrote when prompted in my profile at the campaign website.
Why I support Barack Obama: I support Barack Obama because I believe we need a President who believes in the American people--one who can inspire us to start believing in ourselves again. We need a national leader who is thoughtful, who can listen to a variety of viewpoints in a deep way, who can bring people together rather than drive them apart. I support Barack Obama because of his opposition to the war. I support him because he believes in diplomacy. I support him because I think the world he wants for his daughters is the world I want for my son--one in which the US is strong, but not arrogant; where we have a healthy economy that is not built on exploitation; where people are treated with dignity and respect without regard to gender, race, class or creed; where the environment is our treasure, not our plunder; where we try, and think, and work, and hope, and work some more.
