Cruz won Iowa and it made no difference if it was 20 points or 1 but if Trump gets 28% instead of 40 he loses?? 40 % was never predicted . If he wins by 1 point he still wIns as any other candidate would.
Making excuses already?
If Trump wins, he wins, just as Cruz actually won Iowa, no matter what Trump and his people say.
However, if he gets a mere 28 percent after polling much higher than that, it will be the second straight state in which he will have underperformed. Should that occur, it should be of some concern to the Trump people.
