TRiUMPh demonstrated and overperformed polls. Mission accomplished. I suspect Trump’s underperformance relative to the polls in Iowa was due to an excessive undecided Rubio leaner effect, an especially good Cruz ground game, and complacency among supporters of the Donald due to his sound lead in the polls. Today, we will have to suffer with this no longer. Bush&Kasich are doomed; their overperformance in New Hampshire is fundamentally a good thing.
