How does the u. s. constitution's structure reflect the values of the founding fathers?

I believe that although the constitution has not changed much since it was written, but I do believe that however, the interpretation of the constitution has changed over time. I believe that the Founding Fathers would be a little shocked if they were to travel through time and see how the US is right now. 

A. democrat, republican, whig, other.(the democratic and republican parties are the main 2 american political parties, the whig party was popular among the early presidents, and the “other” option allows for outliers)
