His new book is out. It seems to me that the Left Behind Series had more to do with what Evangelicals thought would happen, according to their collective speculation since the Seventies, starting off with the airplanes will lose their pilots trope. The books had politics sprinkled throughout, but was meant to be a novelization of popular apocalyptic imagination of the late Twentieth Century, relatively vague in political terms.
It seems that LaHaye is reversing his focus on theme because,
These books sound like a Wingnut jack-off fest. Unlike his former co-author, his current co-author is Religious Right connected. The premise is a private weapons industry phenom saved New York from North Korea, and the government wants control of the defense system he designed. He acquires the moral and material support of a group of self-fashioned "Patriots", in a "near future" when the government has shifted left.
Also the Vice President is a Feminist with a devious agenda, and not to be trusted. It's like he developed this premise in July 2008, when there was a thin prospect of a Hillary Clinton Vice-Presidency, but didn't bother changing it after the developments of the following month. Or he wants to make his readers nervous of a female Democrat in high office.
I could see him not bringing in the Rapture until about halfway through the book series, if not later, just to show how Liberals will destroy America as a means to pander to the paranoid in his audience, while his previous series had a more geo-political focus.
