both the south and north, including Calhoun, who became Jackson's vice presidential running mate, and New York Senator Martin Van Buren. Meanwhile, Adams's support from the Southern states was eroded when he signed a tax on European imports, the Tariff of 1828, which was called the "Tariff of Abominations" by opponents, into law. Jackson's victory in the presidential race was overwhelming. He won 56 percent of the popular vote and 68 percent of the electoral vote. The election ended the one-party system that had formed during the Era of Good Feelings as Jackson's supporters coalesced into the Democratic Party and the various groups who did not support him eventually formed the Whig Party. The political campaign was dominated by the personal abuse that partisans flung at both candidates. Jackson was accused of being the son of an English prostitute and a mulatto, and he was labeled a slave trader who trafficked in human flesh. A series of pamphlets known as the Coffin Handbills accused him of having murdered 18 white men, including the soldiers he had executed for desertion and alleging that he stabbed a man in the back with his cane. They stated that he had intentionally massacred Native American women and children at the Battle of Horseshoe Bend, ate the bodies of Native Americans he killed in battle, and threatened to cut off the ears of congressmen who questioned his behavior during the First Seminole War. Jackson and Rachel were accused of adultery for living together before her divorce was finalized, and Rachel heard about the accusation. She had been under stress throughout the election, and just as Jackson was preparing to head to Washington for his inauguration, she fell ill. She did not live to see her husband become president, dying of a stroke or heart attack a few days later, and was buried on Christmas Eve. Jackson believed that the abuse from Adams' supporters had hastened her death, stating at her funeral: "May God Almighty forgive her murderers, as I know she forgave them. I never can." Presidency (1829–1837) Inauguration Jackson arrived in Washington on February 11. His first concern was forming his cabinet. He chose Van Buren as Secretary of State, his friend John Eaton as Secretary of War, Samuel D. Ingham as Secretary of Treasury, John Branch as Secretary of Navy, John M. Berrien as Attorney General, and William T. Barry as Postmaster General.
