The first part of the process is controlled by the political parties in each State and varies from State to State. Generally, the parties either nominate slates of potential electors at their State party conventions or they chose them by a vote of the party's central committee. This happens in each State for each party by whatever rules the State party and (sometimes) the national party have for the process. This first part of the process results in each Presidential candidate having their own unique slate of potential electors....

The winning Presidential candidate's slate of potential electors are appointed as the State's electors—except in Nebraska and Maine, which have proportional distribution of the electors. In Nebraska and Maine, the State winner receives two electors and the winner of each congressional district (who may be the same as the overall winner or a different candidate) receives one elector. This system permits Nebraska and Maine to award electors to more than one candidate.
