U.S. Senator Hillary Clinton's Web site includes veterans, children and women among her top issues.
John Edwards' site lists blacks, Asian-Americans, Pacific Islanders, Latinos, the elderly and young people among his concerns.
U.S. Senator Barack Obama talks about all of the above, but of the three front-running Democratic presidential candidates, he's the only one with a permanent place on his Web site for America's indigenous peoples.
''First Americans for Obama is a community of people dedicated to bringing positive change to American politics and breaking the cycle of partisan ideology,'' according to the First Americans for Obama page on his Web site.
''Perhaps more so than any population, American Indians are painfully aware of the need for change. Tribes have experienced firsthand the lack of progress under prior administrations. Please use this Web site to learn about Obama's policy initiatives supporting tribal peoples, to spread the word, and to involve your family, friends and community. Together, we can bring in a new generation of politics - one based on respect, honor and unity.''More
