The researchers David E. Campbell of Notre Dame and Robert D. Putnam of Harvard started interviewing a cohort of 3,000 Americans in 2006. Using this longitudinal data set, they explore the attitudes of Tea Party supporters years before the Tea Party existed. As they explain in a New York Times Op Ed:
Beginning in 2006 we interviewed a representative sample of 3,000 Americans as part of our continuing research into national political attitudes, and we returned to interview many of the same people again this summer. As a result, we can look at what people told us, long before there was a Tea Party, to predict who would become a Tea Party supporter five years later. We can also account for multiple influences simultaneously — isolating the impact of one factor while holding others constant.
What they found was that the Tea Party was neither a grass roots movement, nor was it people inspired by the recession. Rather, it consisted of long-term right wing Christian conservatives:
Our analysis casts doubt on the Tea Party’s “origin story.” Early on, Tea Partiers were often described as nonpartisan political neophytes. Actually, the Tea Party’s supporters today were highly partisan Republicans long before the Tea Party was born, and were more likely than others to have contacted government officials. In fact, past Republican affiliation is the single strongest predictor of Tea Party support today.
What’s more, contrary to some accounts, the Tea Party is not a creature of the Great Recession. Many Americans have suffered in the last four years, but they are no more likely than anyone else to support the Tea Party. And while the public image of the Tea Party focuses on a desire to shrink government, concern over big government is hardly the only or even the most important predictor of Tea Party support among voters.
So what do Tea Partiers have in common? They are overwhelmingly white, but even compared to other white Republicans, they had a low regard for immigrants and blacks long before Barack Obama was president, and they still do.
More important, they were disproportionately social conservatives in 2006 — opposing abortion, for example — and still are today. Next to being a Republican, the strongest predictor of being a Tea Party supporter today was a desire, back in 2006, to see religion play a prominent role in politics. And Tea Partiers continue to hold these views: they seek “deeply religious” elected officials, approve of religious leaders’ engaging in politics and want religion brought into political debates. The Tea Party’s generals may say their overriding concern is a smaller government, but not their rank and file, who are more concerned about putting God in government.
