box at the Park Theatre (Manhattan, New York). This was in response to a speech that Eacker had made on July 3, 1801, that was critical of Hamilton. Philip and his friend both challenged Eacker to duels when he called them "damned rascals". Price's duel (also at Weehawken) resulted in nothing more than four missed shots, and Hamilton advised his son to delope (throw away his shot). However, both Philip and Eacker stood shotless for a minute after the command "present", then Philip leveled his pistol, causing Eacker to fire, mortally wounding Philip and sending his shot awry. Election of 1800 Burr and Hamilton first came into public opposition during the United States presidential election of 1800. Burr ran for president on the Democratic-Republican ticket, along with Thomas Jefferson, against President John Adams (the Federalist incumbent) and his vice presidential running mate Charles C. Pinckney. Electoral College rules at the time gave each elector two votes for president. The candidate who received the second most votes became vice president. The Democratic-Republican Party planned to have 72 of their 73 electors vote for both Jefferson and Burr, with the remaining elector voting only for Jefferson. The electors failed to execute this plan, so Burr and Jefferson were tied with 73 votes each. The Constitution stipulated that if two candidates with an Electoral College majority were tied, the election would be moved to the House of Representatives—which was controlled by the Federalists, at this point, many of whom were loath to vote for Jefferson. Although Hamilton had a long-standing rivalry with Jefferson stemming from their tenure as members of George Washington's cabinet, he regarded Burr as far more dangerous and used all his influence to ensure Jefferson's election. On the 36th ballot, the House of Representatives gave Jefferson the presidency, with Burr becoming vice president. Charles Cooper's letter On April 24, 1804, the Albany Register published a letter opposing Burr's gubernatorial candidacy which was originally sent from Charles D. Cooper to Hamilton's father-in-law, former senator Philip Schuyler. It made reference to a previous statement by Cooper: "General Hamilton and Judge Kent have declared in substance that they looked upon Mr. Burr to be a dangerous man, and one who ought not be trusted with the reins of government." Cooper went on to emphasize that he could describe in detail "a still more despicable opinion which General Hamilton has expressed of Mr. Burr"
