Which two states have a different system for allocating electoral votes?

Maine and Nebraska have a unique system for allocating their electoral votes, differing from the winner-takes-all approach that the majority of states use. In these two states, electoral votes are allocated through a proportional representation mechanism. Specifically, they assign one electoral vote to the winner of each congressional district within the state, with the remaining two electoral votes awarded to the overall state-wide winner. This means that it's possible for a candidate to win electoral votes even if they do not win the majority of votes statewide, as they can secure victories in individual congressional districts.

This system allows for a more nuanced representation of voters' preferences and can lead to scenarios where electoral votes are split between candidates, thus reflecting a diversity of political views within the state. Most other states, such as Texas, California, New York, Florida, Ohio, and Michigan, follow the traditional winner-takes-all method, which does not provide this level of granularity in electoral allocations.
