The Persistence of Racial Resentment - NYTimes.com: Although there was plenty of discussion during the 2012 presidential campaign about the Hispanic vote and how intense black turnout would be, the press was preoccupied with the white vote: the white working class, white women and upscale whites.
Largely missing from daily news stories were references to research on how racial attitudes have changed under Obama, the nation’s first black president. In fact, there has been an interesting exploration of this subject among academics, but before getting to that, let’s look back at some election results.
In the 16 presidential elections between 1952 and 2012, only one Democratic candidate, Lyndon B. Johnson in 1964, won a majority of the white vote. There have been nine Democratic presidential nominees who received a smaller percentage of the white vote than Obama did in 2008 (43 percent) and four who received less white support than Obama did in 2012 (39 percent).
