Political Science analysis problem

Here is the details; please write 3 paragraphs only.

Part III: Answer the following question in three to five paragraphs (50 points total):

In your educated opinion, what was the major obstacle that America had to overcome to make the nation the “more perfect union” it is today? Note: if you think that America has yet to overcome that obstacle, you may argue that instead.

*Remember you are arguing your educated opinion, which, in this case will be your thesis. The thesis should then be supported what you learned in this class: primary sources, readings, and lecture. Prepare this answer at home, then commit it to memory so you can write it during the final.
