"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."
