Huck was trending downwards way before that. He is very socially conservative but too many remember how he governed in Arkansas. He seemed to like to spend money just like the left and he seemed to like big government a little too much as well.
He’s not a bad guy. I’ve heard him speak several times and he has made some really good points during this campaign - but really, he had little chance and I’m sure he knew that from the beginning. It looks (to me anyway) like he was just running to increase his political capital - perhaps for other reasons than gaining the nomination.
I tend to agree with your assessment.
