No doubt you've heard about the "six degrees of separation" concept. Well, I'm not sure by how many "degrees," but it turns out, according the the research of a young girl from Salinas, California, that all U. S. presidents except one are related. So, in the future, we need not be so surprised to hear this president or that is related to his (or her) diametrically opposite political rival, suggesting, perhaps, our political persuasion is not mapped on the genome. Thus, it holds true once again, we are all more alike than we are different. To see what she did and how she came to her conclusions, you can see the article, "Local student finds all but one U.S. presidents are related," in the Santa Cruz Sentinel.
