The results should be pretty intuitive. The probability of supporting gay marriage rises if a voter:
is Democratic
is liberal
is white
is young
is female (although the effect of gender is very minor once other categories are accounted for)
is more highly-educated
comes from a higher-income household
lives in an urban area
is atheist or reports having no religious affiliation
if religious, is a non-evangelical Protestant, rather than an evangelical, Mormon or Catholic.
