Some conservative commentators are wary of accepting Trump’s claim of rigged polls.

“I’m not gonna (get) caught in a trap again of automatically rejecting what’s out there but all the while understanding, this is a different election,” Rush Limbaugh said on his nationally syndicated radio show Monday.

“Look, there’s nobody that wants these polls to be more wrong than I do. And in 2012, I sat here every day and told you they were wrong because they were using the wrong turnout model, that they were not factoring turnout in 2010. All those tea party people.”

In addition, Trump mischaracterizes a common polling practice that really is known as oversampling.

Trump seized on a 2008 email from the account of John Podesta, then and now a top Clinton adviser.

“WikiLeaks also shows how John Podesta rigged the polls by oversampling Democrats, a voter suppression technique,” Trump said. “And that’s happening to me all the time.”

In the email, another operative wrote, “I also want to get your Atlas folks to recommend oversamples for our polling before we start in February. By market, regions, etc. I want to get this all compiled into one set of recommendations so we can maximize what we get out of our media polling.”

However, that was describing the common polling practice of surveying more members of one group to get a statistically meaningful deeper look at that one bloc. Polls often, for example, will get only a sliver of Hispanics in the final total, too few to draw any conclusions about their thoughts. So a poll will also seek a broader sample, an “oversample,” of Hispanics. But those numbers are not traditionally used in the overall poll.

“He’s saying oversampling is having too many of a particular group when actually it’s done because you have too few,” said Lee Miringoff, the director of the Marist Institute for Public Opinion in New York. “Oversample for pollsters is that you’re interested in finding out more about a group you typically don’t get enough of. You interview more of the group, but it doesn’t enter into your overall totals.”

Trump hasn’t sworn off all polls. Campaigning in Tampa, Florida, earlier this week, he touted an Investor’s Business Daily poll Sunday that showed him leading Clinton by 43-41 percent in a four-way race that includes Libertarian Party candidate Gary Johnson and Green Party nominee Jill Stein.

“The most accurate poll for the last three presidential elections, by far, has us up 2 points nationwide,” Trump told the crowd.

But his lead faded into a statistical tie in an Investor’s Business Daily tracking poll the next day.
