"Any strategic change by Trump in New Hampshire would be an admission that he did something wrong in Iowa"

“Any strategic change by Trump in New Hampshire would be an admission that he did something wrong in Iowa,” said Jim Dornan, a Republican operative and former Trump adviser. “The Donald Trump I observed would never admit that.”

According to veteran Republican pollster Tony Fabrizio, the Iowa caucuses held several avoidable disappointments for Trump. “If I were Trump’s folks and looked through the entrance poll data I would commit SUICIDE,” he wrote in an email.

Fabrizio cited entrance poll data — now adjusted to reflect vote totals — showing that Trump had lost Iowa caucus-goers who are concerned about government spending to Cruz, 27 percent to 19 percent, as well as those who are angry at the federal government by a narrower margin.

Fabrizio also cited results showing Rubio winning 30 percent of caucus-goers concerned about the economy to Trump’s 24 percent. “Losing economic voters to Rubio is a joke,” he wrote.
