We sometimes say the president is the most powerful man in the world, but this isn’t really the case. The president of the United States of America must work within a system of checks and balances that is intentionally inefficient and forces compromise so that no one person can take too much power. George Edwards, professor of political science, explains the limits of the president’s power. A president’s promises on the campaign trail often get deflated after they get into office because they have to contend with congress. Party politics often makes it difficult or impossible to compromise, as senator Lindsey Graham found out the hard way when he got trampled by an elephant.
