The term PRESIDENT PRO TEM (3 letters) and TEDM (4 letters) are both titles given to a presiding officer of a legislative body. The President Pro Tem is the temporary president of the Senate, while the TEDM is the Temporary President of the House of Delegates. Both positions are responsible for managing the day-to-day operations of their respective chambers, including setting the agenda, recognizing members to speak, and ruling on points of order. They also serve as a tie-breaking vote in the event of a deadlock.
