According to the New Yorker,  

"Obama’s election was one of the great markers in the black freedom struggle. In the electoral realm, ironically, the country may be more racially divided than it has been in a generation. Obama lost among white voters in 2012 by a margin greater than any victor in American history. The popular opposition to the Administration comes largely from older whites who feel threatened, underemployed, overlooked, and disdained in a globalized economy and in an increasingly diverse country. Obama’s drop in the polls in 2013 was especially grave among white voters. “There’s no doubt that there’s some folks who just really dislike me because they don’t like the idea of a black President,” Obama said. “Now, the flip side of it is there are some black folks and maybe some white folks who really like me and give me the benefit of the doubt precisely because I’m a black President.” The latter group has been less in evidence of late."[MORE] and [MORE]
