Midterms are a chance for polling industry to redeem itself, says pollster

Pollster Mark Penn said Wednesday that pollsters have a chance to redeem themselves in November's midterm elections after predicting President TrumpDonald John TrumpIllinois governor says state has gotten 10 percent of medical equipments it's requested Biden leads Trump by 6 points in national poll Tesla offers ventilators free of cost to hospitals, Musk says MORE would lose in 2016. 

"Could there be another upset? Could we be wrong? Pollsters don't think so. They think when it comes to the House, they have it covered. If pollsters are wrong again, wow, the entire profession will have egg on its face," Harris Poll co-director Mark Penn told Hill.TV's Joe Concha on "What America's Thinking." 

"This is the chance for the polling profession to redeem itself by making conventional wisdom, Republicans lose the House and Republicans hold on to the Senate because that's what they're telling America," he continued. 

Penn's comments come as polls show Democrats leading in a series of House races, while Republicans appear to lead in contentious Senate races. 

The Real Clear Politics polling average on Wednesday showed Republicans trailing Democrats by 7.2 percentage points.
