(Newport News, Va.) — Democrat Ralph Northam’s lead over Republican Ed Gillespie has narrowed in the contest to be Virginia’s next governor, according to a tracking poll released Tuesday by the Wason Center for Public Policy at Christopher Newport University.

Northam, now lieutenant governor, is the choice of 48% of the likely voters surveyed, while former Republican National Committee Chair Gillespie is the choice of 44%.

Libertarian Cliff Hyra polled at 3%, with 5% undecided. The survey’s margin of error is +/- 4.2%.

In the Wason Center’s benchmark poll, released September 25, Northam’s lead stood at 6% (47% to 41%). It grew to 7% (49% to 42%) in the first tracking poll, released October 9.

The current survey is the first in the Wason Center’s tracking series in which Northam’s share shrank as Gillespie’s increased. It is also the first in the series in which Northam’s lead is within the survey’s margin of error.
