The Tariff of 1828 was largely the work of Martin Van Buren (although Silas Wright Jr. of New York prepared the main provisions) and was partly a political ploy to elect Andrew Jackson President. Van Buren calculated that the South would vote for Jackson regardless of the issues, so he ignored their interests in drafting the bill. New England, he thought, was just as likely to support the incumbent John Quincy Adams, so the bill levied heavy taxes on raw materials consumed by New England such as hemp, flax, molasses, iron, and sail duck. With an additional tariff on iron to satisfy Pennsylvania interests, Van Buren expected the tariff to help deliver Pennsylvania, New York, Missouri, Ohio, and Kentucky to Jackson. Over opposition from the South and some from New England, the tariff was passed with the full support of many Jackson supporters in Congress and signed by President Adams in early 1828.
