(Undated) – Indiana lawmakers could vote next month to send a constitutional ban on gay marriage to voters in 2013, but most Hoosiers oppose a ban, according to a new poll.

The Indiana proposal, which also bans civil unions for same-sex couples, already passed the legislature in 2011, but must do so again in 2013 before Indiana voters get their say.

The Hoosier Survey by Ball State University and WISH-TV shows that 54 percent of Indiana residents oppose the constitutional amendment to ban gay marriage while only 38 percent support it. Eight percent were undecided.

According to the poll, support for the legalization of same sex marriage is greatest among the young (69 percent support among those ages 18 to 24) and those with more education (57 percent among those with post graduate training) and is most opposed by older Hoosiers (57 percent among those 65 and older) and those with less than a high school degree (72 percent).

The poll did, however, show that all-out support for gay marriage in Indiana is a toss-up. When asked if they favor or oppose legalizing same-sex marriage in Indiana, 45 percent said they favored it and 45 percent were opposed leaving 10 percent undecided.

Fifty-five percent of Hoosiers support legalizing civil unions for same-sex couples, while 37 percent opposed. Eight percent remained undecided.

The poll, which has a +/- 4.5 percent margin of error, surveyed 602 Indiana residents from November 12-24. The full survey can be found online at http://cms.bsu.edu/Academics/CentersandInstitutes/BowenCenter/PolicyResearch/HoosierSurvey.aspx.
