I’m a bit more equivocal. In the long run, Trump has to prove that he doesn’t have a low ceiling on his support. Getting 30 percent would be better than the 24 percent he got in Iowa, but it’s still in Pat Buchanan range. (In 1996, Buchanan got 23 percent in Iowa, then won New Hampshire with 26 percent of the vote.) The important way it would be helpful for Trump is that a strong showing for Kasich and Bush could keep them in the race longer and prevent party elites from consolidating around Marco Rubio.
