A quote from this article:
http://www.nationalreview.com/campaign-spot/309347/why-are-so-many-pollsters-oversampling-democrats#
Starting in 1992, EVERY Pew poll appears to lean to one direction — always towards the Democrat, and by an average of more than 5 percentage points. Worse this is a reflection of the “final” poll which even the Democratic firm, Public Policy Polling, usually gets right.
October 1988 — Bush 50 Dukakis 42; Actual Result Bush +7.6 (Call this one spot on.)
Late October 1992 — Clinton 44 Bush 34; Actual Result :Clinton +5.5 (Skew against Republican candidate +5.5)
November 1996 — Clinton +51 Dole 32; Actual Result Clinton +8.5 (Skew against Republican candidate +10.5)
November 2000 — Gore 45; Bush 41 (Skew against Republican Candidate +3.5)
November 2004 — Kerry 46; Bush 45 (Skew against Republican Candidate +3.4)
November 2008 — Obama 50 McCain 39 (Skew against Republican + 3.8)
After being wrong in the same direction so consistently, wouldn’t you think that Pew might attempt to adjust their sampling techniques to adjust their techniques to avoid under-sampling Republican voters?
Bear in mind that this is only what happens in the final poll before the election. Polls taken earlier are even less accurate and more skewed.
