via Crashing the Tea Party (NYT) (Worth a full read if you have the time. It’s relatively short.)
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.
