I think Christie was eyeballing the AG seat, where he’d run the whole thing for five or six years and help his “friends” and punish his “enemies”. You kinda see his behavior here at work. The current AG is being used in the same way....as is the EPA.
At this point, zero chance of Christie amounting to anything of a serious nature in the primary except in NY and NJ. Zero chance of him doing anything in Iowa.
Ironically, I also suspected that might have been why Rudy Giuliani launched his comical presidential campaign, too.
The old guard GOP seems to be pushing him already, tho...
