Looking at the numbers its not that there is a new demographic as Obama had 8 million fewer votes from him than in 2008 but 3.5 Million Republicans didn't vote over not liking Romney. http://www.thegatewaypundit.com/2012...2008-and-2004/
See turn out numbers here: http://www.kypost.com/dpps/news/nati...n-2008_7991483
Republicans need to work on getting their base out. Don't get distracted on winning 2% more here or 3% more there. If they had turned out their base they would have won the popular vote by a million votes. Early numbers show they would have pulled away Virgina, CO, FL, and Ohio.
Rrepublicans won Independents heavily.
