text: The state legislatures are responsible for this happening. "Consider that state legislatures are technically responsible for picking electors." Here's an example of what almost happen to president John F. Kennedy. "Back in 1960, segregationists in the Louisana legislature nearly succeeded in replacing the Democratic electors with new electors who would oppose John F. Kennedy." This was a way of not giving John F. Kennedy his earned votes. "(So that a popular vote for Kennedy would not have actually gone to Kennedy.)"
