bragg's case against him, this has been helpful to him. it's put his rivals in an uncomfortable position. it's led republican primary voters who were skeptical to think, wait a second, he's the victim of persecution. he's being attacked. folks are trying to take him off the playing field. these things oddly enough have been helpful at this stage. the question is later on, if there is some alternative, will that lead to a renewed focus? will it lead to the fact there there are a variety of different legal cases, some of which are far more damaging than others? that's the question we don't know the answer to. >> so far he's only been charged. he hasn't been convicted. >> that's right. >> we'll see what happens. guys, thank you very much. coming up, nikki haley is at the center of the most expensive ad war in iowa caucuses history. will it make a difference tonight?
