Debating the Presidency by Richard J Ellis & Michael Nelson Assignment

I need the paper to be 4 pages. the book you use for this essays is ( debating the presidency by Richard J. Ellis), and Michael Nelson. but you can also use other online sources but use the book mostly, like at least 40% of the paper and make sure you have an argument if you wanna compare the presidents you can but not in terms of characters or personalities because someone already took that topic.
