There's A Better Way to Read Political Polls, New Data Analytics Site Says

Interesting...we'll see if it works
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.
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.
