If you want to understand why the federal government is shut down for the first time in 17 years, a good place to start would be Indiana University Professor Clem Brooks and New York University Professor Jeff Manza's just-published paper in the American Sociological Review.
The answer is simple: increased partisanship. This is, on the surface, kind of a "duh!" explanation — just look at the dynamics in Congress, for crying out loud.
But reading the paper, "A Broken Public? Americans’ Responses to the Great Recession," the shutdown appears to be the inevitable result of a dynamic unprecedented in recent decades in which public support for government programs decreased sharply in a time of economic distress. It did so wildly unevenly, with almost all of the decline coming on the Republican side, where support for government programs plummeted to record lows.
The decline in public support for government solutions to social problems between 2008 and 2010 was the was among the largest two-year changes in the last quarter of a century, the authors found. This turn against government programs during the Great Recession is the opposite of the public-opinion shifts in favor of them that characterized the Great Depression. Because it also runs contrary to a number of predictive models about the relationship between the economy, the role of government, and public opinion, the authors delved into why American support for government social programs declined so sharply between 2008 and 2010 — a period when economic anxiety and need were at their highest since the Great Depression.
They tested data from the General Social Survey and two other sources to explore a number of different hypotheses. Was it a reaction against growth in government under Obama — the so-called "government overreach" hypothesis? Lingering racial animus affecting views of a government now headed for the first time by an African-American? The product of a war of ideas in American political life that was shaping public opinion independently of macro-economic circumstances? And what was the role of "motivated reasoning" — the all-too-common intellectual habit of insisting on a belief in the face of contrary evidence, and especially in times of stress?
They systematically tested hypotheses until they were left with one conclusion: The Great Recession caused everyone to double down on what they already believed about the proper role of the individual and the state, with Republican sentiments intensifying more sharply against new government programs than Democratic ones changed in favor. “For several decades now, the Democratic and Republican parties have become more and more distinct when it comes to the laws and policies that U.S. senators, representatives, and presidents support,” said Brooks in a statement. “This polarization is also asymmetric: Republican politicians have moved much faster to the right than Democratic politicians have moved to the left. "
"[W]hy did the U.S. public turn to comparatively lower preferences for government action during the recession?" the study authors ask in their journal aritcle. The "results point overwhelmingly to partisanship .... had only changes in the preferences of partisan identifiers occurred, there would have been a larger drop in overall government policy preferences. The public would have moved even faster away from government support during the critical 2008 to 2010 period."
