Mike Venezia once again uses his winning formula of combining humor with history to make learning fun. Each book in this series is an appealing mix of full-color historical images and photos, Mike's hilarious cartoon-style illustrations, and simple, factual text describing each person's path toward the nation's highest office. These biographies are peppered with humbling and funny anecdotes that bring out the humanity of each of these historical figures and help kids realize that these were real people--not just names from history books. Although most people don't know much about James Polk, many historians think he was one of the better U.S. presidents. Polk did something not many presidents have done. He made a list of things he promised to do and then actually did all of them! President Polk lowered tariffs--taxes on imported goods. He also took the nation's money out of different banks and put it into a national treasury so it would be better protected. Finally, he added more land to the U.S.--1 million square miles--than any other president.
