While African-Americans turned out in numbers in-line with my expectations, Hispanics who now account for 14% of the US population (citizens and non-citizens) continued to lag in turnout. In 2008, Hispanics represented only 9% of the electorate. I was also wrong in thinking that Hispanics would break for Senator Obama by a 3:1 margin. In the end, they broke for Obama by a 2:1 margin. That’s still a ten point improvement over Senator Kerry’s score in the 2004 election.
Asian-Americans, while only 2% of the electorate, also went for Obama by a near 2:1 margin. All other racial groups (non-white) also broke for Obama by a near 2:1 margin. All told ethnic minorities accounted for 26% of the US electorate and they went for Obama by a near 4:1 margin overall. 79.2% of the ethnic vote ended up in Obama’s column while 55% of the white vote went for McCain.
