Trump has to clean up in N.H.

No, he just needs to beat Rubio and Kasich (who for some reason is polling well there) by a reasonable margin. In New Hampshire the danger for Trump is a narrow victory over Rubio. Kasich probably can't escape also-ran status at this point. Rubio, with the whole GOPe behind him, might.
As Cruz supporters are relishing at the moment anything that tarnishes Trump's image as a winner helps everyone else. A slim margin in New Hampshire would be worse for Trump than losing Iowa is.
