I’ve always believed that America offers opportunities to all who have the industry and will to seize it. Sen. Obama believes that, too. But we both recognize that though we have come a long way from the old injustices that once stained our nation’s reputation and denied some Americans the full blessings of American citizenship, the memory of them still had the power to wound.

A century ago, President Theodore Roosevelt’s invitation of Booker T. Washington to visit — to dine at the White House — was taken as an outrage in many quarters. America today is a world away from the cruel and prideful bigotry of that time. There is no better evidence of this than the election of an African-American to the presidency of the United States. Let there be no reason now for any American to fail to cherish their citizenship in this, the greatest nation on Earth.
