If the president can no longer serve, who becomes president?

The Vice President becomes the president if the current president can no longer serve. This principle is established in the Presidential Succession Act of 1967, which outlines the line of succession should the president be unable to fulfill their duties due to death, resignation, removal, or incapacitation. The Vice President is specifically designated as the next in line to ensure continuity of government and leadership.

The other roles listed, such as the Speaker of the House, Chief Justice, and Secretary of State, do play significant roles in the government but are not the immediate successors to the presidency. The Speaker of the House comes after the Vice President in terms of presidential succession, illustrating the structured order established to maintain a stable governmental operation. The Chief Justice leads the judicial branch, while the Secretary of State manages foreign affairs, neither of which holds a direct position in presidential succession as designated by the Constitution.
