A friend, not usually one to be overtaken by excessive enthusiasm,said, during the few days after the 2008 election, that it meant that the United States was finally entering the post-racial period we thought might come about after the end of the civil war, after Brown v Board of Education, or, at the very least, after the enactment of the Civil Rights and Voting Rights Acts of the mid 1960s and the abolition of the poll tax. We may be on our way there but, at least so far, we have not come close to that day, despite the election of President Obama.
