text: The first reason why deciding the president should be left to the Electoral College is because the slate electors are voted on by the people. Each party chooses a slate of electors trusted to vote for the party's nominee. There is the possibility that the winner of the electoral vote will not win the popular vote. Even though that happens very rarely. Voters are needed when choosing slate electors because a single persons vote may effect who is chosen fo the position. The Electoral College is decided on by voters and wheather or not someone votes may change who becomes the slate elector for your state.
