What would it take for a presidential candidate to win an election with fewer votes from states?

To win a presidential election with fewer votes from states, a candidate would need to effectively leverage the Electoral College system, where winning states by narrow margins can yield more electoral votes than losing larger states by wider margins. Strategic campaigning in swing states, focusing on voter turnout, and capitalizing on demographic advantages could also play a significant role. Additionally, a strong ground game and targeted messaging can help mobilize key voter blocs to secure necessary electoral votes despite overall lower popular support.
