A fair question. We found quite a few things we did not expect, and we liked many of the people we spoke withm and say as much in the book. We have compared our conclusions and evidence with those of scholars who are very conservative in their personal political views, and we agree on the key findings. That is how the scholarly community works. As for conservatives studying a leftist movement, they would need to follow the same standards of gathering evidence and sharing it with other scholars. Our book is not a political screed, and we restrict our evaluations to the conclusion. You may notice if you read the conclusion, that we say the citizen activism in the Tea Party is "wonderful" even as we raise questions about a lack of tolerance. We say that Tea Partiers know the political process even better than liberals often do. Yet when we heard things that were just plain factually false, we say so.
