"Aaron Burr had a fine mind, personal charm, and the knack of winning votes. These qualities carried him to the United States Senate, and almost to the Presidency. In 1800 the federal electors divided their votes equally between Burr and Jefferson for thirty-six ballots before they finally named Jefferson President and Burr Vice President."
"In his political activities Burr had incurred the enmity of Hamilton, although outwardly the two men were friends. In 1804, during the course of a hot campaign for the governorship of New York, the ill-feeling came to the surface. Hamilton, it was said, had asserted that Burr was a 'dangerous man and one who ought not to be trusted with the reins of government.' Burr demanded an explanation; Hamilton made an evasive reply. Burr issued a challenge; Hamilton accepted, though reluctantly. The duelists met at Weehawken, New Jersey, on July 11, 1804."
