Peter D. Wigginton was born in Springfield, Illinois, and later moved to Wisconsin, where he completed preparatory studies and attended the University of Wisconsin–Madison, studying law. He practiced law in Wisconsin and California, serving as district attorney of Merced County. Wigginton transitioned to public service, being elected to Congress as a Democrat, and later contested and served in the 45th Congress. He founded the American Party, a nativist third party, and was its vice presidential nominee in 1888.

Peter D. Wigginton's political identity is marked by a striking commitment to nativist principles, as evidenced by his founding of the American Party. His legislative career, which included a contested seat in Congress, suggests a willingness to challenge established norms. Wigginton's educational background hints at a respect for intellectual rigor, yet his political actions seem to prioritize exclusionary immigration policies. This juxtaposition invites deeper inquiry into how Wigginton reconciles these seemingly disparate values.
