Pew is known as the most accurate poll out there
Except for all of the other pollsters. Read this, and know the truth - you are being manipulated.
Specifically, regarding the Pew poll:
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)
Any poll, like this one, that assumes a 9% advantage for Democrats over Republicans, is pure garbage. It is published only to sway liberal and Roney-hating opinion.
So that's why they weight it to give a seven point gimmee to the Democrats.
By the way, the "accuracy" is a scam. Allow me to explain.
not really...Rasmussen has shown himself to be the best...he was beaten up on Freep four years ago when his polls consistently showed McLame 6/7pts behind obozo but he was on the money...
