Final answer:
Presidential electors send their votes to the President of the Senate after casting their ballots.
Step-by-step explanation:
After presidential electors have voted, they send the count of their votes to the President of the Senate. This occurs when the electors meet in their respective states to cast their ballots by vote for President and Vice-President. Following this, they make distinct lists of all persons voted for, along with the number of votes for each, and transmit these lists sealed to the seat of the government of the United States. It is the duty of the President of the Senate to open all the certificates in the presence of the Senate and House of Representatives and then the votes are counted. The Electoral College plays a critical role in determining the outcome of a presidential election.
