选举团是由选民选出的公民团体，他们在选举团为总统和副总统的选举投票。政党通常在州级党大会上或在党的中央委员会上提名选举人。

在大选中投票的选民实际上是投票选这些选举人，选举人的名字根据其将支持的候选人被列在选票上。选举团最终选出总统，而不是通过普选票。

但当一个选举人偶尔投票选一个非自己最初支持的候选人时，实际的选举团投票通常被视为一种形式。

你还记得最近有一次大选，一位候选人输了普选票，却赢了选举团选票吗？

US-General Election - What is the electoral college?  

The Electoral College is the group of citizens elected by voters to cast ballots in the electoral college for the president and vice president.  

Political parties usually nominate electors at state party conventions or by a vote of the party’s central committee.  Voters in the general election are actually voting for these electors, who are listed on the ballot based on which candidate they will support.

The Electoral College, not the popular vote, ultimately elects the president, but while an elector occasionally votes for a different candidate than the one they initially supported, the actual Electoral College vote is usually seen as a formality.

Can you remember a recent Presidential Election in which a candidate lost the popular vote, but won the Electoral College vote?
