The New Republic is a liberal American publisher focused on domestic politics, news, culture, and the arts, with ten magazines a year and a daily online platform. Founded in 1914 by several leaders of the progressive movement, it attempted to find a balance between "a liberalism centered in humanitarian and moral passion and one based in an ethos of scientific analysis".

Modern liberalism in the United States is based on the combined ideas of civil liberty and equality with support for social justice. It is one of two major political ideologies of the United States. Economically, modern liberalism supports government regulation on private industry, opposes corporate monopolies, and supports labor rights. Its fiscal policy opposes any reduction in spending on the social safety net, while simultaneously promoting income-proportional tax reform policies to reduce deficits. It calls for active government involvement in other social and economic matters such as: reducing economic inequality, increasing diversity, expanding access to education and healthcare, regulating economic activity, and environmentalism. Modern liberalism is a large and mainstream ideology in the Democratic Party and nation. Modern liberalism was formed in the 20th century in response to the Great Depression. Major examples of modern liberal policy programs include the New Deal, the Fair Deal, the New Frontier, the Great Society, the Affordable Care Act, and the Infrastructure Investment and Jobs Act.
