you wish it was ONLY Black voters that made the difference, read it & weep!
Look at the basic breakdown of Mr. Obama’s victory, according to exit polls (which may yet be revised). He won 93 percent of African-Americans, 71 percent of Hispanics, and 73 percent of Asians. He took 55 percent of the overall female vote, down only one percentage point from his comparable 2008 showing.
