are very dedicated in doing it. and donald trump has a lot of support in iowa. i mean, what are people telling you, why are their convictions so strong? he's got a lot of loyalty, a lot of loyalty from last time around, a lot of loyalty from the four years he spent in the white house. he has a pretty good organisation nowadays, but the leads are extraordinary. i mean, the polls suggest here that he has a 28—point lead. it's been higher than that at various points as well, more than 30 points. that is unheard of in these kind of processes. no—one has actually voted yet, so we'll see if that translates, but i'd be amazed if that disappears. i don't think that's very likely. and that's reflected across the nation in terms of the republican vote. he has captured, quite simply, the republican party. there's no question about that, it's donald trump's party now, and in many ways, the other candidates here are just duking it out for second place.
