Final answer:
In the Election of 1800, pivotal states like New York and Pennsylvania went to the Republicans, with Jefferson and Burr each receiving seventy-three electoral votes, leading to a decision by the House of Representatives that resulted in Jefferson's presidency.
Step-by-step explanation:
The Electoral College vote in the Election of 1800 was greatly influenced by key states. New York and Pennsylvania were especially pivotal, as their electoral votes both went to the Republicans. Thomas Jefferson and Aaron Burr, representing the Republican Party, each secured seventy-three electoral votes, whereas John Adams received sixty-five, and Charles Cotesworth Pinckney obtained sixty-four.
This outcome meant that the Republicans had defeated the Federalists, but the tie between Jefferson and Burr necessitated a decision by the House of Representatives to select the president. Ultimately, Thomas Jefferson won the presidency after Alexander Hamilton influenced some Federalists in the House to vote in his favor. This event is often referred to as the Revolution of 1800 because it signaled a peaceful transition of power from one political party to another.
