I will not vote for Christie, not in the primary and not in the general election if he is the nominee. I’ll vote 3rd party or stay home. Christie would be an improvement over the Hildebeast, but not by much - at least he seems like a competent executive.
Oh, there is so much more than voting that can be done in the political cycle and much of it is spiritual.
Winning Christie over to saner positions in preference to pouring vitriol upon him could pan out to be a plus in the long run.
