The fact that one is left-leaning (socialist) and the other is right-leaning (libertarian) is common knowledge. That political divide had to be hidden to keep up the discipline's appearance of being objective and scientific, so there was a flurry of attempts in the twentieth century to synthesize the two approaches. But the neoclassical renaissance dethroned Keynesianism in the 1970s, supporting the conservatism of Reagan and Thatcher. And the neoclassical confidence in the stability of capitalism is still the dominant attitude among economists, based on the pseudoscience of the flashy mathematical models and the bogus rational choice theory.
