Nate Silver calls out PPP for liberal bias on gun control poll

Things got tense between the Democratic-leaning Public Policy Polling and the former New York Times’ campaign forecaster, Nate Silver, after PPP admitted that it didn’t release the results of a survey predicting defeat for pro-gun control lawmakers facing recall in Colorado.

“VERY bad and unscientific practice for @ppppolls to suppress a polling result they didn’t believe/didn’t like,” Silver, who now works at ESPN, tweeted.
