Rather than simply averaging the overall result of major national polls pitting President Obama against Mitt Romney (as is done on sites like Real Clear Politics), The Washington Dispatch digs into the cross-tabs of data behind major national polls (those that freely publish the necessary data breaking down responses by party identification), and averages each candidates’ share of the vote among Republicans, Democrats, and Independents. Then, these shares are applied to the actual turnout by party identification (as measured by CNN’s comprehensive exit polling of between 13,000 and 18,000 respondents for the 2004, 2006, 2008, and 2010 elections) for the past four national elections. To calculate poll numbers for The Washington Dispatch’s official head-to-head match-up between Barack Obama and Mitt Romney, each candidates’ average share of the vote by party affiliation is applied to the average turnout by party affiliation over the past four national elections.
