From the pollsters at Gallup, who notice some surprising things:
Tea Party supporters skew right politically; but demographically, they are generally representative of the public at large. That’s the finding of a USA Today/Gallup poll conducted March 26-28, in which 28% of U.S. adults call themselves supporters of the Tea Party movement.
As I’ve previously noted, one should be careful about reading too much into a single poll. However, these results are far from surprising.
It would be interesting to know if any political cause in the last generation (30 years or so) has had such a even cross-section of Americans as its supporters. Perhaps the Gallupers can check their archives.
