Polling Site Search Engine (high quality)

Introducing the 'Polling Site Search Engine (high quality)' -- which queries polling sites with a reputation for high quality polling/reporting, solid scores in prediction, and do not engage in strong partisanship.  Pew Research matches these criteria.

The search engine uses 20 polling sites, only those that have "Very High" or "High" rankings for reporting/factuality/prediction as measured by 'Media Bias/Fact Check.'  

While Civiqs.com has a "high" reporting ranking, it is rated "left" in polling bias, not falling into the centrist range (left-center, least biased, or right-center) -- so it is excluded. 

Sites like Gallup are excluded because they fall below the "high" reporting/factuality ranking. Gallup still has a solid site ranking at "mostly factual." But MBFC says of Gallup: "FiveThirtyEight, an expert on measuring and rating pollster performance, has evaluated 84 polls by Gallup, indicating they are accurate 69% of the time or Mostly Factual."

Also available is the 'Polling Site Search Engine (good quality)' which includes all sites ranked "mostly factual" or higher. No sites are excluded because of partisanship. This provides a larger set of good quality polling data to query. Both Pew Research, civiqs.com and Gallup match these criteria
