No GOP candidate scored as high as double digits, a sign of the most wide-open nomination contest in modern times. Wisconsin Gov. Scott Walker was a narrow leader at 9%, followed by former Florida governor Jeb Bush at 8%, Texas Sen. Ted Cruz at 7% and Kentucky Sen. Rand Paul at 5%.
In response to the open-ended question, no one named Mitt Romney, the party's 2012 presidential nominee. He led the field at 16% in the USA TODAY/Suffolk Poll in January, but he has since said he doesn't plan to run in 2016.
