What does the Pledge of Allegiance express loyalty to?

The Pledge of Allegiance expresses loyalty to the flag of the United States. When individuals recite the Pledge, they are symbolically affirming their allegiance to the nation represented by the flag. The flag stands as a powerful symbol of American unity and values, including freedom, democracy, and justice. By pledging allegiance to the flag, individuals are also pledging their support for the ideals and principles that the flag represents.

The other options do not provide the same level of direct connection to the concept of loyalty as the flag does. The United Nations represents international cooperation rather than national loyalty. The Constitution is the foundational legal document of the United States, but the Pledge specifically centers on the flag as a symbol of national identity. Lastly, while loyalty to the President is important in the context of support for elected leaders, the Pledge focuses on an overall commitment to the nation rather than an individual leader. Therefore, the flag serves as the central symbol of allegiance in the Pledge of Allegiance.
