Until the 1990s, American electoral politics were divided ideologically, between the opposing ideas of liberalism and conservatism. Now we have team politics: Democrat versus Republican, my party right or wrong.

Those things don't happen now. Americans back their party the same way they back their favorite sports team — with automatic, stupid loyalty.
