historically loved intellectual, smart, young charismatic figures. barack obama was one. you could argue bill clinton was one and pete buttigieg certainly is one as well. and i think what the similarity is, there are a couple of similarities but one of them i point to is when people go see him and they learn more about him and they hear him speak and watch his interviews, a lot of democrats like what they have to see. so for him, the encouraging number in the polls is that two-thirds of democrats in the iowa caucus poll are willing to look at other options. he's already high in the polls but i think his hope is to do what barack obama did and what john kerry did is to make a move when there is an opening and there is always an opening in the iowa caucus in the final months. >> let's look at the brand-new iowa poll and warren, sanders and buttigieg and biden all there. and, chris, it seems like you look at that and say, okay, warren, sanders, biden -- buttigieg?
