A new poll shows Representative Jacky Rosen with a 4-point lead over incumbent Senator Dean Heller.
The Emerson College poll released Monday found Rosen opening up a small lead over Heller among likely voters surveyed, 49 percent to 45 percent.
It represents a shift from Emerson’s last poll from mid-October, which had Heller ahead by 7 points.
The poll also found Democratic candidates leading in Nevada’s two competitive House races.
In Nevada’s race for governor, Democrat Steve Sisolak leads Republican Adam Laxalt 48 percent to 47 percent among respondents to the Emerson survey.
Polls are open for voting in Nevada until 7 p.m. Tuesday.
