>> there are couple of things. obviously what happened this past week with mrs. clinton's health probably had a little bit of impact. mr. trump had some opportunities that he didn't take complete advantage. i think the biggest thing that has happened is mrs. clinton's campaign has lost a little bit of momentum. if you are looking at the polls, it's very clear that this raises tightening into what is basically a time. -- eight high -- a tie. of the we can look at a two- person race we will not have a two-person race. we have a four-person race and when you see that neither of the two leading candidates are getting close to 50%. it's a tight race and i think the biggest explanation has to do with the fact that both of the candidates are also strongly disliked by a lot of voters. the fact that there is a tight expresses some of the frustration.>> it's been about three weeks since donald trump retooled his campaign, have you noticed any difference?
