Losing Iowa was part of Trump's plan:
He even hinted us in his post-Iowa speech. He's crashing the election with no survivors. As a republican, you're basically supposed to lose Iowa if you truly want to win the nomination and the presidency.

The farm speech:

>Bought The Farm
>phrase: refers to someone deceased in a military accident or operation. Phrase predates World War II, but came into common use at that time due to the large numbers of training casualties due inexperienced pilots/crewmembers trained in aircraft that are much less reliable than today. Common accidents in rural areas would result in aircraft crashing into barns, fields, or rural property, resulting in damages. The US Government would compensate the affected property owners with checks to pay for damages, or in some cases condemn land contaminated with undetonated/unlocated munitions/weapons, in effect "buying the farm".
Losing Iowa was a strategic wake-up call for Trump's supporters to go and vote instead of just rallying.
