If Christie is tarnished, does that impact the GOP's moderation efforts?

Huntsman isn’t moderate at all: he is highly conservative. His problem is that he is way too neurotypical for the Republican primary electorate. I quote myself:

You can accept the scientific consensus on global warming. You can accept evolution. But both at the same time? That’s a bridge too far for the Republican electorate. Add to this his foreign policy credentials such as an Ambassadorship to China under Obama combined with fluency in Chinese and his candidacy is basically hopeless.
