Check out the exit polls — the breadth and depth of the Trump victory is extraordinary. He won among just about every part of the electorate, no matter how you slice it. Maybe New Hampshire is uniquely suited to Trump (certainly the terrain is more favorable than Iowa), but he is not a force to be trifled with. Candidates, groups, and donors who think they can let Trump run free for a while because it allegedly serves their temporary interests are playing with fire.
