He won't get the support he did in 2012. Third place at CPAC wasn't a big deal, because at that point, the margin was 1% between him and 4th, and so on. I doubt he'll run, anyway. He hasn't really stayed in the news.
I think it all depends on the health of his daughter Bella. There is one thing nobody can take away from Rick. He is a family man. So much so, that he puts family before campaigning and certainly before politics. If she is in good health, I think he runs, but he won't put a presidential campaign before the health of his daughter, or anyone else in his family.
