What are some ways the electoral college can change?

The Electoral College can change through constitutional amendments, which require a two-thirds majority in both the House of Representatives and the Senate, followed by ratification from three-fourths of the states. Alternative reforms include the National Popular Vote Interstate Compact, where states agree to allocate their electoral votes to the candidate who wins the national popular vote, bypassing the need for a constitutional amendment. Additionally, states could individually decide to change their methods of allocating electoral votes, such as using proportional representation instead of a winner-takes-all approach.
