Married registered voters prefer Republican challenger Mitt Romney over Democratic President Barack Obama by 54% to 39%, according to Gallup data collected from June to August.
On the other hand, nonmarried voters break strongly for the president over Romney, 56% to 35%.
Marriage is a significant predictor of presidential vote choice even after income, age, race, gender, education, religiosity, region, and having minor children are statistically controlled for. [cont.]
