Dr. Ben Carson remains one of the big question marks hovering over the 2016 field of Republican presidential candidates. Despite knowing very few of his actual policy beliefs (aside from some troubling gun control remarks that he has since recanted) conservatives are eager for the doctor to make a run. It's easy to see why. He's obviously extremely intelligent, has an unassailable resume, and looks "presidential" in a way that Barack Obama has never been able to manage. In short, he appears to be the kind of grown-up who stands in stark contrast to the current administration - even if he's yet to outline all of his positions.
