The Rasmussen survey released on Sunday found Merkley leading Wehby 47 percent to 37 percent among likely voters in Oregon. Five percent said they preferred another candidate, and 11 percent said they were undecided. The poll came less than a week after Wehby won the GOP nomination for Merkley's Senate seat.
Before election night, two police reports concerning Wehby surfaced. One report said that Wehby's ex-boyfriend had accused her of stalking him. Another report also said that Wehby's ex-husband accused her of ongoing harassment.
The survey was conducted May 21 to May 22 among 750 likely voters. It had a margin of error of plus or minus 4 percentage points.
