Uh Oh, Pollsters Are Screwing Up Again | The Daily Caller:
"Most national pollsters are back churning out biased and misleading poll numbers after recovering from their shock over President Donald Trump’s 2016 election victory, according to The Daily Caller News Foundation Investigative Group analysis.
“I do know inherently there is a Democratic bias in the polls.
And most of them will deny it” says Raghavan Mayur, an independent pollster who is president of TechnoMetrica, which leads the polling operations at Investor’s Business Daily.
A national financial news organization, IBD was one of the few polling organizations to predict a Trump victory, and it has accurately called the last four presidential elections.
“Typically, the mainstream media and the major polling companies will never admit their bias to you,” Mayur said.
“This is like an alcoholic not admitting to using alcohol. They are in denial.”
Democratic pollster Patrick Caddell agreed with Mayur, saying “there was a couple of days of shock. And then they moved on because what they could not do is to get to the bottom of their own polling bias.”
...When polling the public, most mainstream firms “overloaded for Democrats, underloaded for Republicans and conservatives,” said Francis Coombs, managing editor of Rasmussen Reports.
John Zogby, another independent pollster, also told TheDCNF he sees significant Democratic polling bias.
“I am a liberal Democrat, but I always felt that other polls oversampled Democrats and undersampled Republicans,” he said.
Zogby is the founder of the internationally acclaimed Zogby poll and a senior partner at John Zogby Strategies."
