>> that's true. there's always the dark horses. >> which one -- i think the dark horses have been running a long time, running hard and they're not getting anywhere. when it comes to marco rubio, however, jeb bush and ben carson trump is letting it rip. here's some of his attack on the other candidates. >> i think rubio doesn't have it. if you look at his stance on immigration he's very weak. you look at rubio, he wants open borders. that's why i don't understand why he's doing as well as he's doing, which isn't that well, frankly. we need strength now. we don't need ben carson. he's a wonderful man. i like him a lot. but we don't need somebody that doesn't make a deal. he's never employed anybody. maybe a nurse. >> jeb bush says he's not a good -- why would he admit that? i watched him. "i'm not an entertainer." he goes, "i'm not a good talker. i don't speak well. i don't debate well. i don't do anything well. but you should vote for me." that's jeb bush. why would you say these things? this is what's going to negotiate with china? that is what's going to negotiate with iran?
