Our Founding Father was a step-dad. George Washington helped raise the biological children of Martha Washington, and they had no children together. But they did have a loving, 40-year marriage.
Our current president is the father of two girls. One likes to photo-bomb their cute inaugural moments. The Obamas are in the 20th year of their marriage.
Click through the slideshow for a sample of the most powerful men in America getting cozy with their sweethearts.
