If the United States is really the 'Land of the Free' where anyone can become president, you would expect that the American presidents [George Washington to Joe Biden] would express that genetic diversity. This has not been the case. The presidents of the United States are as much a royal dynasty as anything in Europe, from whence their bloodlines came. By branching out far enough on the presidential family tree, the dedicated researcher will find that all 45 American presidents share kinship, belonging to the same general ancestry, often called the 13th Illuminati bloodline, the Merovingian line, and/or the Windsor-Bush bloodline. If you go deeply enough into the genealogical research you will find that all 45 American presidents are descended from one person — Emperor Charlemagne, the eighth century King of the Franks.
