In the United States, a presidential candidate can win the popular vote but lose the Electoral College because the presidency is determined by electoral votes rather than the national popular vote.12

The system functions through the following mechanisms:

  • Winner-Take-All Allocation: In 48 states, the candidate who wins the statewide popular vote is awarded all of that state’s electoral votes. This means a candidate can win several states by narrow margins while losing others by large margins, potentially accumulating a majority of electoral votes without securing the most votes nationwide.123
  • State-Based Representation: Each state is allotted a number of electors equal to its total number of senators and representatives in Congress. A candidate who wins many states with smaller populations or wins key states by slim margins can reach the required 270 electoral votes even if their opponent receives a higher total number of individual votes across the country.1432
  • Exceptions: Maine and Nebraska use a different method, allocating electoral votes by congressional district with a bonus for the statewide winner, though the overall impact of the Electoral College remains the same.13
