What is the main purpose of the Constitution as stated in its preamble?

The main purpose of the Constitution as stated in its preamble is to "form a more perfect union." This phrase reflects the founders' intention to create a unified and cohesive nation that would be stronger and more effective than the collection of individual states under the Articles of Confederation. By establishing a framework for a federal government, the Constitution aims to enhance cooperation among states, improve governance, and address issues that could not be effectively managed by states acting independently.

This foundational goal underscores the aspiration for unity, stability, and the creation of a government that is capable of functioning for the common good of all citizens. The preamble sets the tone for the entire document by outlining the broader objectives that guided the framers in drafting the Constitution, such as promoting justice, ensuring domestic tranquility, providing for the common defense, and securing the blessings of liberty.

The other options, while relevant to the Constitution and its function, do not encapsulate the overarching purpose articulated in the preamble. For example, protecting the rights of individual states focuses on their sovereignty rather than the unity sought by the founding document. Similarly, government accountability and the powers of the President are important aspects of the Constitution but are more specific goals rather than the primary purpose highlighted in the introduction of the document.
