text: The voters choose a canditate in the electoral college but they can always change their votes. For example, "Back in 1960, segregationists in the Louisiana legislature nearly succeeded in replacing the Democratic electors with new electors who would oppose John F. Kennedy." stated in source two. Basically, If you want a republican president to win you would vote for a republican represetative of the electoral college, but thats not always the truth. Voters can not control the mind of a representative, in a few seconds they become of member of the oppsoing sides and thus they have your vote. This is known as unfair use of your vote that can obviously not be taken back.
