Which polls have been most accurate over last 10 years?
Of pollsters that have been active in Colorado this year, SurveyUSA, which polls for the DenverPost/ 9News survey, ranks the highest, third, of 261 polling companies, Dave Kopel reports over at http://www.WhoSaidYouSaid.com. Ciruli, which is known as the pollster for Colorado Democrats, ranks an impressive 4th in terms of accuracy. Another firm that works mostly for Democrats and left-wing blogs, Public Policy Polling, ranks 18th. Rasmussen Reports claims to be independent but is accused of favoring Republicans, ranks 20th. CNN/Opinion research is 39th, Magellan is 69th, Marist Institute is 24th and Fox/Opinion Dynamics is 141st. LINKS: Kopel: Which pollsters are most accurate? By David Kopel.

It is amazing how you even thought of this! Well I might agree that the SurveyUSA which does the polls for DenverPost/9News survey is well graded, because I read the paper and what the pollsters have predicted come to pass in almost the same fashion predictedPosted by Jordan on 11/23/2010 at 08:13 AM
