Polk promised to solidify American control over the Oregon territory. He did it. He promised to acquire California from Mexico. He did it. He promised to adjust tariffs to improve foreign trade; the Walker Tariff dramatically reduced tariffs and improved trade. He promised to take Federal money out of banks and put it into a treasury. He did that too. He also established the Department of the Interior, first new cabinet-level Executive department in over 50 years. Perhaps most impressive of all, he promised to do it all in 1 term and not run for a 2nd. He retired after 4 years after fulfilling EVERY CAMPAIGN PROMISE HE HAD MADE. Quite possibly the only president ever to do so. Good thing, too, since all his hard work had totally worn and aged him and he died less than 4 months after he left office.
PUT HIM ON THE LIST!!!!!
