They are. The electoral college is who officially votes and makes the president the president. This is the fulfillment of article II, section 1:
"Each State shall appoint, in such Manner as the Legislature thereof may direct, a Number of Electors, equal to the whole Number of Senators and Representatives to which the State may be entitled in the Congress: but no Senator or Representative, or Person holding an Office of Trust or Profit under the United States, shall be appointed an Elector."
We call this process the "Electoral College", and it happens at every election.
