In the second tier of contenders, Sen. Ted Cruz (Texas) takes 6 percent support, followed by businessman Donald Trump at 5 percent, former Texas Gov. Rick Perry at 4 percent, former Hewlett-Packard CEO Carly Fiorina at 4 percent, and New Jersey Gov. Chris Christie and former Arkansas Gov. Mike Huckabee pulling 3 percent each.
“Bush, Rubio, Walker and Paul seem to be separating themselves slightly from the rest of the field but this is likely due to press attention rather than any real campaign work,” said Andrew Smith, Director of the UNH Survey Center.
