Not all of the polls by Public Policy Polling have been accurate; the company has had its share of inaccurate results. Among the most notable of its mispredictions were that of the 2008 Democratic presidential primary in Pennsylvania<16> (in which it predicted an Obama victory; Clinton ultimately won by 9-10%), and that in the 2009 special election in New York's 23rd Congressional District.<17> In New York, the official Republican candidate dropped out of the race and endorsed the Democratic candidate while PPP was in the field interviewing voters. PPP's results showed the conservative candidate with a large lead; in the end, the Democrat won with a 2.3% lead.
