Final answer:
The author aims to inform readers about the Electoral College, a system where 538 electors cast the formal votes to elect the U.S. president based on state popular votes, with a focus on the 'winner-take-all' approach and possibilities of winning the presidency without the national popular vote majority.
Step-by-step explanation:
The author's purpose suggested by the text is to inform and explain the workings of the Electoral College in the United States presidential election process. The Electoral College is a unique system where each state has electors equivalent to its number of Senators and Representatives in Congress, which are later responsible for formally electing the President and Vice President. The text emphasizes that this system does not rely on a direct popular vote but on the electoral votes that are often pledged to the candidates based on statewide popular votes, with a total of 538 electors and a minimum of 270 electoral votes required to win the presidency.
In most cases, states adopt a 'winner-take-all' approach, with the exception of Maine and Nebraska, which use the congressional district method. Despite the common plurality rule in most American elections, the Electoral College system can result in a candidate winning the presidency without having received the most popular votes nationwide, as demonstrated in the 2000 and 2016 elections.
