The U.S. Constitution says "Each State shall appoint, in such Manner as the Legislature thereof may direct, a Number of Electors . . ."

The normal process of effecting change in the method of electing the President is specified in the U.S. Constitution, namely action by the state legislatures. This is how the current system was created, and this is the built-in method that the Constitution provides for making changes. The abnormal process is to go outside the Constitution, and amend it.
