Carson since:
1. He’s running on a platform of being a mentsch unlike his opponents who are politicians, except for Trump who is campaigning on the platform of being a jerk (which is probably an act).
2. His views on social and economic issues are most compatible to our own, and he will favor a muscular foreign policy (as will most conservatives) but with caution (his background is mildly pacifistic, just enough that he can be trusted not to go crazy). Unlike the professional politicians, he is focused on principles rather than specific policies, and is open to working to get things accomplished.
3. If any of the other Republicans run, Hilary will win comfortably (it might be close with Rubio, with Trump, Cruz or Bush it will be a major Democratic landslide).
