A new poll released Wednesday by right-leaning Civitas showed Dalton ahead of former Congressman Bob Etheridge in the Democratic gubernatorial race.
In the poll of North Carolina Democrats likely to vote in the primary election or who have already voted, Dalton was the choice of 32 percent, with Etheridge picked by 27 percent.
State Rep. Bill Faison of Orange County was named by 4 percent.
"About two weeks before the May 8 voting, more than a quarter of those polled remained undecided," said Brian Balfour, director of policy at Civitas. "So even though it seems to have boiled down to a two-man race, the final result is still up for grabs."
Earlier this week, a survey by left-leaning Public Policy Polling showed that the race is now basically a tie with Dalton at 26 percent to 25 percent for Bob Etheridge and 5 percent for Bill Faison.
A month ago, Etheridge led by 11 points. Since then, Etheridge has dropped a point while Dalton has gained 11.
