wrestle with this question all the time. what ben carson is talking about today, not only is not a radical position to take but it's one that is part of an intellectual mainstream. now what he is doing also though, is creating a problem for frontrunner donald trump because while trump has been silent substantially or muted on these issues in the wake of his troubles last week about the guy, from the question and stuff and birther and the yikes, while trump has stepped back on that carson is stepping out into that space. if you want to be the candidate in the republican party who takes toughest line on sharia law, if you want to be a candidate in republican party, who takes hardest line on many see, invidious forces of radical islam around the world and united states that is a real issue for a subset of republican party. if you galvanize those folks behind you that would be a powerful in the primary process. martha: chris, thank you very much. >> you bet. bill: the ben carson story lives another day.
