The battle between Jeffersonian Democracy and Jacksonian Democracy defines and dominates the U.S. political spectrum, with Westerners and freesoilers going Jacksonian instead of forming the incipient Republicans who in OTL would become the party of industry and big business in the Gilded Age.
The U.S. is the seat of mainstream Libertarianism, with both parties' history of being for free trade and unionism and against both national banks and private financial speculation coloring a genuinely libertarian economy of small businesses - with federations and syndicates of traditional and cooperative industries being the norm. Small firm and family agriculture, and the ideal of every family having a small plot of land, are matters of national pride.
Britain is the seat of Communitarianism - the Red Tories and the Methodist Labourites united and replaced the Liberal Party as the main opposition to the Tories. The Tories, already moralistic protectionists and not economic liberals, were merely a few steps away from essentially becoming an opposing communitarian party with a few differences. The Liberals, now the Libertarians, are a minor party; having to compete with handful of messily organized atheistic, technocratic, and otherwise anti-moralistic groups.
In Communitarian lingo, those with no respect for the chains of community that God links between his fellow men are dubbed "Atheists"; including the United States (despite the fact that most Americans are Deists, including Christian Deists, Judeo Deists, and Islamic Deists - the main African American religion).
