Heading into the final days of the Senate primary, Secretary of State Elaine Marshall has opened up her lead, according to a new poll.
Marshall now leads former state Sen. Cal Cunningham by a 28-21 percent margin, according to a new survey by Public Policy Polling. The poll was taken Saturday and Sunday of 803 likely voters and had a margin of error of 3.5 percent, Rob Christensen reports.
The survey showed Marshall with a larger lead than a week ago, when she led Cunningham by a 26-23 percent margin. The major reason, the pollsters found, was a shift of black voters to Marshall.
But Tuesday's primary remains highly fluid with 33 percent of those polled still undecided.
It should not be noted that polls in low turnout primaries are particularly unreliable because of the difficulty of measuring who will actually show up to vote. The changes are also within the margin of error.
The survey concluded that the primary is a two-person race. Chapel Hill lawyer Ken Lewis received 9 percent support from those surveyed, followed by Marcus Williams with 4 percent, Ann Worthy with 3 percent and Susan Harris at 2 percent.
It is still not clear whether any candidate will be able to pull 40 percent of the vote on Tuesday to avoid a runoff.
"Beyond the fact that Marshall and Cunningham will be the top two finishers on Tuesday we can't say how this will shake out," said Dean Debnam, president of Public Policy Polling. "The high level of undecideds means you can't count Cunningham out, and there's still a distinct chance we'll be going another seven weeks to get a winner."
The survey found that 70 percent of Cunningham's supporters are completely committed to him, compared to 60 percent of Marshall's supporters. The largest number of undecided voters was in the Charlotte area where Cunningham began running TV ads last week, but where Marshall has not run any TV ads.
