The Gapology of the Obama Vote in the 2008 Democratic Presidential Primaries

In their competition for the 2008 Democratic nomination, Barack Obama and Hillary Clinton developed distinct demographic bases of support. This study will analyze the demographic divides in the 2008 Democratic presidential primaries, focusing on the “gaps” that emerged in the support of Obama. Obama’s demographic bases of support were African-Americans, younger voters, educated voted, those with no religion affiliation, wealthier voters, males, political independents, and ideological liberals. Despite the considerable amount of attention given to the gender gap, a number of demographic gaps were more significant. Race was by far the most important gap and a key component of Obama’s victory was his tremendous support from African-American voters.
