Which power would get a president greater legislative power than the office currently has would it be power of a line item, veto power of executive privilege, power to call a special session or power to recommend legislation?

The power that would give a president greater legislative power than the office currently has would be the power to recommend legislation. This power allows the president to propose new laws or changes to existing laws, giving them a direct influence on the legislative agenda and potentially shaping the direction of policy debate in Congress. While the other powers listed (line item veto, veto power of executive privilege, power to call a special session) also have significant impacts on the legislative process, the power to recommend legislation is unique in that it gives the president the ability to actively shape the policy agenda and prioritize certain issues for consideration by Congress.
