e of the reasons Americans were fascinated by the idea of the United States stretching from "sea to sea" was because it symbolized the country's expansion and growth. It signified the belief in Manifest Destiny, the idea that America was destined to expand westward and spread democracy and freedom. Additionally, having control of land from coast to coast provided economic opportunities for trade and commerce, as well as opened up new territories for settlement and development. It also allowed for the establishment of a unified nation with a strong presence on the world stage. This idea of a vast and powerful nation stretching across the continent appealed to Americans' sense of pride and nationalism.
