After a deserved honeymoon, the new president is likely to find that the intensity of this bitterness has only gathered. Because of the ideological polarization of cable television news, talk radio and the Internet, Americans can now get their information from entirely partisan sources. They can live, if they choose to, in an ideological world of their own creation, viewing anyone outside that world as an idiot or criminal, and finding many who will cheer their intemperance. Liberals have perfected this machinery of disdain over the past few years. Given the provocation, the same approach is likely to be turned against the new president by the right as well.
