Avoiding political statements:

Happy Girl already gave a great explanation of the Declaration of Independence, but I wanted to add a historical note.

Although Jefferson was the main writer of the Declaration, Franklin was one of the other three committee members, and he did change some of Jefferson's wording. So I am sure they had some arguments when it was written.

(I teach a class on the American Revolution at the beginning of each school year, so I have both the Declaration and the U.S. Constitution on my iPod. The apps were free!)
