Yeah, I'd vote for Carson.
I love Carson and personally I find his policies great... But he is too strong of a christian and that isnt what this country needs right now. As it is I feel we need a president who is as unbiased as is possible on issues that often have a religious tilt, I.E. abortion.
As as strong of a christian as I am, you cant try to force a christian policy on a athiest, muslim, jew, or occultist.
