Bob Altemeyer, who's researched the subject for over 20 years. Altemeyer wrote a book on the subject that I highly recommend. It's available for free here: https://drive.google.com/file/d/0BxxylK6fR81rckQxWi1hVFFRUDg/view
If it turns out you do not like this book, blame John
Dean. You never would have heard of my research if
he had not recently plowed through my studies, trying
to understand, first, various people he knew in the
Nixon White House, and then some leading figures of
the Republican Party of 2004. John Dean is quite a
guy. I think I offended him once by addressing him as
AHonest John,@ which I meant in the sense of AHonest
Abe.@ John strikes one with his candor and openness. I
treasure his friendship as much as I treasure his
unfailing help. Some of his closest friends, I have discovered, go back to his high
school days. I think that says a lot about a person, especially given what John went
through in the 1970s. The former counsel to the president@ has campaigned endlessly
on behalf of my research, making it known wherever he could. This book was his
idea, and you would not be reading it if he had not kept "bringing me up on the stage"
with him as he talked about his Conservatives Without Conscience.
