Edward V. Robertson spent his formative years in Cardiff, Wales, before emigrating to the United States in 1912. He settled in Park County, Wyoming, where he raised livestock and operated a mercantile business in Cody. Robertson served as a life trustee of Cody General Hospital and held leadership roles in the Wyoming Republican Party. He represented Wyoming on the Republican National Committee before being elected to the United States Senate, where he introduced legislation to grant full citizenship to Native Americans.

Edward V. Robertson's political identity is marked by a unique blend of historical advocacy for Native American rights, rooted in his early life experiences and engineering background. His legislative efforts to grant full citizenship to Native Americans reveal an ideological commitment to inclusivity and civil rights, which is intriguing given his conservative political affiliations. Robertson's approach to policy-making appears to be highly localized, reflecting his deep ties to Wyoming and Oregon, where he spent most of his life. This localized focus is further complicated by his broader national political involvement, suggesting a nuanced and perhaps ideologically agile stance. His ability to navigate and influence both local and national spheres adds an intriguing layer to his political persona.
