Carly Fiorina, Ben Carson, and Mike Huckabee have all become increasingly popular among GOP primary voters since announcing their candidacies in May, making some of the largest gains in the latest WSJ/NBC news poll.



Fiorina’s support levels leapt from 17 percent in April to 31 percent in June; Carson’s from 31 percent in March to 50 percent in June; and Huckabee from 52 percent in March to 65 percent in June.



Jeb Bush and Marco Rubio have remained at the top of the pack in recent months, at 75 and 74 percent respectively.



Scott Walker and Rand Paul both saw slight decreases in support, with Paul going from 59 percent in April to 49 percent in June.

Another interesting finding: only 4 percent of primary voters are concerned that there are too many candidates from legacy families. 33 percent are concerned that wealthy individuals and corporations will influence the election.



16 percent worry that nothing will change, no matter who wins.
