I find genetics and genealogy fascinating. I think there's so much to explore in the area of how much our genetic makeup contributes to our personalities/tendencies throughout our lives as opposed to our upbringing.
With that, I found it incredibly intriguing that Barack Obama's lineage has ties to quite an impressive list of leaders (regardless of whether they were good leaders):
Obama has a prolific presidential lineage that features Democrats and Republicans. His distant cousins include President George W. Bush and his father, George H.W. Bush, Gerald Ford, Lyndon Johnson, Harry S. Truman and James Madison. Other Obama cousins include Vice President Dick Cheney, British Prime Minister Sir Winston Churchill and Civil War Gen. Robert E. Lee.

Is there a "leadership gene" that runs through the leaders of the world? Many have said so. I don't know. I'm just a lawyer with no scientific background at all. But it's an interesting thing to ponder on a lazy Sunday evening, no?
Maybe someone will do the research one day. Maybe someone already has. If you know of such research, I'd be much obliged to hear about it.
