Republican Sean Duffy and Dem Julie Lassa released competing polls Tuesday in their pivotal 7th CD match-up.
Lassa's poll, conducted by the D.C.-based firm Garin-Hart-Yang Research, shows Duffy leading 42 percent to 41 percent, within the margin of error of plus or minus 4.4 percentage points.
The telephone survey of 504 likely voters was conducted Sept. 26-27. Seven percent of those polled said they would vote for independent candidate Gary Kauther, and 10 percent were undecided.
Lassa leads among two key demographic groups, seniors and college graduates, according to the poll. Among seniors, Lassa leads Duffy 49 percent to 37 percent; among college grads, she leads 45-39.
The polling memo notes that Duffy's record as Ashland County district attorney was "extremely troubling" to the poll respondents. Lassa has been attacking Duffy on the issue in a TV ad over the last week. In the ad, the county's assistant DA says Duffy's campaigning for the congressional seat took him away from the job.
After WisPolitics posted the Lassa poll, Duffy's campaign released its own survey showing him up 47 percent to 34 percent.
The poll of 400 likely voters was conducted Sept. 21-22 by Alexandria, Va.-based Public Opinion Strategies. The poll has a margin of error of plus or minus 4.9 percent.
The poll memo says Duffy has a 49-26 lead among independents; 64 percent believe the country is on the wrong track.
"Senator Lassa's campaign is based on lying negative attacks on Sean because she seeks to hide her job killing career politician record from voters -- and I wouldn't trust this poll anymore than voters can trust her lies about Sean," Duffy spokeswoman Wendy Riemann said of Lassa's poll.
And a new poll from the Republican National Congressional Committee has even better news for Duffy. The survey, taken of 400 likely voters on Sept. 15 and 16 by Fabrizio, McLaughlin and Associates, has Duffy with a 52-38 lead over Lassa. The poll also has a margin of error of plus or minus 4.9 percent.
