To give a bigger sense of why this is such an important number for Romney, consider this: In 2008 Obama won the national popular vote by 7.2 percent overall. If you assume equal turnout in 2012 as 2008 (39 percent Democrats, 32 percent Republicans, and 29 percent independents) but take Obama’s 8 percent win with independents and give it Romney, that 7.2 percent 2008 margin drops to 2.6 percent. If Romney can get Obama’s lead down to 2.6 percent before they even chip away at the giant turnout advantage Democrats had in 2008 (or win over some Democrats to Romney), it is going to be almost impossible for Obama to win.
