Richard McMullen, born in Porters near Glasgow, Delaware, cultivated a diverse professional background before entering public service. He gained early experience in the tanning and leather industry and founded the Standard Kid Company. Transitioning into public service, he served on the Wilmington City Council and various commissions. McMullen was elected Governor of Delaware in 1936, where he focused on public works projects during the Great Depression and labor reforms. His tenure included revising "blue laws" and endorsing the Fair Labor Standards Act.

Richard McMullen's political identity is marked by a blend of progressive economic policies and a surprising willingness to revise traditional governance norms. His support for public works during the Great Depression and endorsement of the Fair Labor Standards Act reflect a commitment to economic stability and worker rights. Yet, McMullen's revision of Delaware's "blue law" to ease Sunday restrictions reveals an unexpected flexibility in his approach to governance. This juxtaposition of progressive economic measures with a more conservative stance on social regulations hints at a highly localized, strategic approach to policymaking.
