Written by Branden Hart Tuesday, 16 October 2007 Lynne Cheney said in an MSNBC interview that, while researching her husband s genealogy for her new book, she discovered that Dick Cheney and Barack Obama have at least one thing in common: an ancestor. This isn't the first time Obama's ancestry has been in the news: the Chicago Sun-Times stated last September that he shares an ancestor with President Bush as well. This won't change whether Mrs. Cheney plans on supporting Obama in his presidential bid, according to the linked CNN article. Question for you CNN: why would it? Why would anyone think that some revelation about an 18th century relation would change the voting allegiance of the woman married to one of the most influential Republicans in the past century? Family unity is important, but is such a remote connection going to change the vote? I don't think so.
