big tax break for you as well. the trump campaign said they want this to be a revenue neutral proposal and reduce the deficit. one of the ways they'll do that, they'll do a one-time 10% tax on corporate profits. they're hoping that will inspire companies to move any money that's overseas back here in the u.s. that will help generate a little revenue. as you said, all of this happens, donald trump's number substantive approach as ben carson is gaining on him in the polls. let's take a look at the new "wall street journal"/nbc news poll. donald trump still ahead of the pack with 21% but ben carson right behind him at 20%. you see there other rivals are gaining, marco rubio, carly fiorina. fiorina's rise came from dash marks to 11%. jeb bush at 7% in the october poll. in june he was at 22%. >> sara, thank you very much.
