Actually would like carson above Rubio therefore minimizing the number of delegate won in early states awarding to % of tally. More for anti establishment — less for establishment
Carson's campaign looks like a pyramid scheme....and he's going to walk away with some big bucks...destined for his own charity.
The more establishment candidates in the race the better. If it weren't for Christie, Kasich, Jeb, and Carly, Rubio rather than Cruz would probably be at #2. On the other hand, if Carson dropped out or his voters lost interest, I'm not sure where they would go. The more anti-establishment types may go for Trump, the more Evangelical for Cruz, while his PC establishment vote (probably about half of his support) would probably go to Rubio or Jeb.
