This NYT report on the Trump campaign in Iowa shows serious shortcomings- a failure to organize a grassroots effort and setup the organization to get people to the voting booth. This is particularly needed for Trump's base of people without a college degree and under 45 years of age, as supporters most likely to vote are evangelicals, those with a college degree and over 45 years. Evangelicals form a base of support for Ted Cruz who has also organized the best effort of all candidates among evangelicals.
