Final answer:
In 48 out of the 50 states, a winner-takes-all approach is used wherein the candidate who wins the most votes in those states gets all of the Electoral College votes. Maine and Nebraska are the only states that use a different method, dividing their electoral votes partly by congressional district outcomes.
Step-by-step explanation:
In 48 of the 50 states, the candidate who wins the state's popular vote wins all of the Electoral College votes for that state. The two exceptions to this rule are Maine and Nebraska, which allocate their electoral votes using the congressional district method. In these states, the overall state popular vote winner receives two electoral votes, and one electoral vote is awarded to the popular vote winner within each congressional district.
