here. she is talking about a middle class tax plan. it is aimed at a group that they did not perform well in 2016 but also medicare for all. it takes you to the left certainly here but to both of you, because i'm curious, give me your review of that policy as well. >> i would say it is interesting that the democratic candidates seem to be jumping in together on medicare for all. i haven't seen her explain the economics of that. i don't know that she's is most well suit today do that. it would be warren's lane. i haven't seen any democrat make the math work on that. so i think there will be some negotiation and waiting in a field this big to see who gets ahead of explaining heart issues like that first and this speaks to the vagueness you pointed out when it come to harris is that she will wait and see i would think. >> you have to do that.
