In this very thread, we have people claiming that the Tea Party is either far-right, moderate, libertarian/Ron Paulist, or all of the above. Which only goes to show it is a protest movement, not an organized political party. People think that it is whatever they wish it were. That's especially true for Nancy Pelosi and a certain White House staffer, who wanted it to be a neo-Nazi movement.
Unlike some, I won't claim to know what kind of people make up the Tea Party, or what ideology they profess. I know who I saw, and what the signs said, and that's about it.
Or maybe there's a credible study somewhere, of Tea Partyer thought and opinion?
