Both Mr. Crane and Mr. Kibbe said in addition to swaying middle-of-the-road voters, Mr. Johnson can also win over disaffected supporters of Sen. Bernard Sanders who are fed up with politics as usual.
"Our operations in Iowa continue to grow, and we anticipate wild swings in the polls, just like four years ago. We'll be ready," Mr. Kibbe says. "Rand is unique because of his track record and leadership on these issues. Once we get through these flavors of the week and the field narrows, Rand will emerge as the anti-establishment choice."
