I came across another article by the same author in a very roundabout way just a few days ago. It was very interesting. It tried to make the case that Abraham Lincoln had Jewish ancestry by virtue of his Melungeon ancestry. If it's true, Joe Lieberman would not be the first president with Jewish ancestry if he ever realized his dream to be president. I also read that Eisenhower had Jewish ancestry, as did a couple of other presidents, although I can't remember which ones right now.
