I took the pledge 2 weeks ago to buy the book, which I did at Borders this week. They are trying to push it onto the best sellers list. I've got to finish Outliers first (tonight) and then I'll start Founder's Second.
Outliers is also very good, though not a "political" book it does explain why some people and some peoples excel while others are just also-rans.
Also checkout this organization which is marketing Halbrook's book. Haven't had a lot of time to check them out but they're against Eric Holder for 2nd Amendment reasons.
