Honestly, the Reagan/Bush43 comparison was not one I'd come across before this book, but Lou and James Cannon definitely make a strong case for how Bush channeled Reagan in a lot of his domestic policy decisions before pulling the rug out from the whole idea and showing how, if that was his intent, he failed miserably. Where the comparison is truly apt is more in their approach to decision-making, which was the same: make a decision based on personal beliefs/ideology and then ask your staff to find post-facto justifications (and to ignore any contradicting information). Bush's examples in this regard (Iraq, the War on Terror, torture) are more glaring than Reagan's (Iran Contra, SDI), but that's more a difference of degree. Highly recommend this one.
