The poll showed 46 percent of likely voters say they would back Greenfield if the election were held today, while 43 percent say they would back Ernst.
The poll, which surveyed 674 likely voters June 7-10, has a margin of error of plus or minus 3.8 percentage points, underscoring how tight the race could be going into the November election.
The poll found that Greenfield, like most Democrats, polls higher among women and non-religious voters.
Among non-religious voters, 71 percent backed Greenfield and 19 backed Ernst, and among women, 54 percent back Greenfield and 34 percent backed Ernst.
Republicans and Democrats largely responded to the survey along party lines, with Independents more likely to back Greenfield than Ernst, 42 percent to 38 percent.
The Cook Political Report rates the Senate race as “lean Republican,” but a survey released last month by the left-leaning firm Public Policy Polling showed Ernst leading Greenfield by just 1 point.
