Answer:
Some delegates were opposed to having a president to lead the executive branch because they feared the president could become a tyrant. These delegates were called Anti-Federalists.
Step-by-step explanation:
The anti-Federalists saw the position of president as a similar to the monarchy, and feared that the president would become a tyrant who imposed his will without limits, as had previously happened with the British monarchy. Therefore, they felt more comfortable with the previous organization, created by the Articles of the Confederation, where a collegiate Congress exercised executive power.
