Hopefully Mr Bush will not be the last white president because, just as now Mr Obama is seen as the best by many, a time may come when the colour of the person's skin (or gender) is of less importance than their politics. Thus the best person may be a white woman, a black man, a hispanic woman, an asian man, or even a white man-- and the one with the most dynamic, positive plan for the future wins!!

Now that's a good aim for the future.
