AND OBAMA OVERPOLLS BECAUSE OF THE BRADLEY EFFECT?:
2012 U.S. Electorate Looks Like 2008 : Composition of electorate by race, age, gender essentially the same (Jeffrey M. Jones, 10/26/12, Gallup)
Gallup identifies likely voters using a series of seven questions that ask about current voting intentions and past voting behavior. The resulting sample of likely voters has proven to give a generally accurate prediction of the final election outcome. For example, in 2004, Gallup's final likely voter estimate (before undecideds were allocated to the candidates) showed George W. Bush with a two-percentage-point advantage over John Kerry in an election Bush won by just over two points. And Gallup's final 2008 estimate showed Barack Obama outpolling John McCain by 11 points, a slight overestimate of Obama's seven-point margin of victory. [...][T]he largest changes in the composition of the electorate compared with the last presidential election concern the partisan affiliation of voters. Currently, 46% of likely voters identify as Democrats or lean Democratic, compared with 54% in 2008. But in 2008, Democrats enjoyed a wide 12-point advantage in party affiliation among national adults, the largest Gallup had seen in at least two decades. More recently, Americans have been about as likely to identify as or lean Republican as to identify as or lean Democratic. Consequently, the electorate has also become less Democratic and more Republican in its political orientation than in 2008. In fact, the party composition of the electorate this year looks more similar to the electorate in 2004 than 2008.
