There’s a Better Way To Read Political Polls, New Data Analytics Site Says

An analysis of recent polling in swing states found that Republicans may be on the cusp of major electoral gains if you consider the pollsters’ historic performance—or, more often, lack thereof. 

The Polling Monitor, a project that launched this cycle, aims to give the public a more accurate understanding of polls that have in previous years been so off—Trump’s 2016 victory took the pollsters and, as a result, most of the public, entirely by surprise, for example, and in 2020 Republican congressional candidates made gains in places no polls suggested they could. The Polling Monitor calls this an “adjustment factor.”

This year, public polling of Pennsylvania consistently shows the Democratic Senate candidate, John Fetterman, leading his Republican opponent Mehmet Oz—but most of the polls conducted have historically overestimated Democratic performance, according to the Polling Monitor’s data analysts. 

A CNN poll released on Monday, for example, found Fetterman leading Oz by 5 points, pulling in an impressive 51 percent of the vote. The Polling Monitor, however, found that CNN polling in Pennsylvania over the past three election cycles is off by an average of 8.8 percentage points in favor of Democrats. It says the poll showing Fetterman up by 5 should really be viewed by the public as an indication that Oz, the Republican, is up by 3.8. A CBS/YouGov poll this week found Fetterman up 51 to 49, but their Pennsylvania polls have been off in favor of Democrats by an average of 6.4, and it should also be viewed as data putting Oz in the lead, according to the analysis.

The effort comes as polling errors have solidified themselves as a fact of life in politics, and the industry’s failures have had major repercussions. Polls are about more than just helping the public know what to expect on Election Day—the results also shape media coverage, voter turnout, and political donations, according to Spencer Abraham, who cofounded the Polling Monitor.

“What the media chooses to cover or not cover is based on polls saying an election is close or not close,” Abraham told the Washington Free Beacon. “We think that the public should be able to understand polling to the best extent they can, and that’s what we try to provide. Our goal is to share and give the world a tool to use to better understand where elections stand.”
