Lincoln's theme? Unification. He held the nation together in the 19th century, when the Union prevailed over the north-south divide. And in the 20th century, the Lincoln Highway did the same thing: It prevailed over the east-west divide by uniting Atlantic and Pacific, the first motorable road to do so. Then, we get to the Lincoln penny, another unifier. [2005]
