It was not so long ago that Texas governor Bush denounced attempts to cut the earned-income tax credit as “balancing the budget on the backs of the poor.” By 2011, Republican commentators were noisily complaining that the poorer half of society are “lucky duckies” because the EITC offsets their federal tax obligations—or because the recession had left them with such meager incomes that they had no tax to pay in the first place. In 2000, candidate Bush routinely invoked “churches, synagogues, and mosques.” By 2010, prominent Republicans were denouncing the construction of a mosque in lower Manhattan as an outrageous insult. In 2003, President Bush and a Republican majority in Congress enacted a new ­prescription-drug program in Medicare. By 2011, all but four Republicans in the House and five in the Senate were voting to withdraw the Medicare guarantee from everybody under age 55. Today, the Fed’s pushing down interest rates in hopes of igniting economic growth is close to treason, according to Governor Rick Perry, coyly seconded by The Wall Street Journal. In 2000, the same policy qualified Alan Greenspan as the “greatest central banker in the history of the world,” according to Perry’s mentor, Senator Phil Gramm. Today, health reform that combines regulation of private insurance, individual mandates, and subsidies for those who need them is considered unconstitutional and an open invitation to “death panels.” A dozen years ago, a very similar reform was the Senate Republican alternative to Hillarycare. Today, stimulative fiscal policy that includes tax cuts for almost every American is “socialism.” In 2001, stimulative fiscal policy that included tax cuts for rather fewer Americans was an economic­-recovery program. …

Extremism and conflict make for bad politics but great TV. Over the past two decades, conservatism has evolved from a political philosophy into a market segment. An industry has grown up to serve that segment—and its stars have become the true thought leaders of the conservative world. The business model of the conservative media is built on two elements: provoking the audience into a fever of indignation (to keep them watching) and fomenting mistrust of all other information sources (so that they never change the channel). As a commercial proposition, this model has worked brilliantly in the Obama era. As journalism, not so much. As a tool of political mobilization, it backfires, by inciting followers to the point at which they force leaders into confrontations where everybody loses, like the summertime showdown over the debt ceiling.
