A group lobbying for passage of a gay marriage ban in Indiana on Wednesday launched two television spots in support of HJR-6, a proposed amendment to the Indiana Constitution which would prohibit the state from recognizing any union other than a heterosexual marriage.

Both of the 30-second spots call on lawmakers to advance the amendment to the November ballot box.

“A small committee will meet very soon at the Statehouse to decide whether you get to vote to protect marriage,” a male announcer says in one of the ads over dark images of the Statehouse as a foreboding soundtrack plays.

The conservative group Advance America is behind the ads.

The group last month was criticized for distributing fliers to churches warning of the “four dangers of same-sex marriage.”

Freedom Indiana, the umbrella group working to derail the proposed amendment, criticized the ads released Wednesday.

“They know a majority of Hoosiers oppose HJR-6 and that our grassroots network is the strongest in Indiana history …,” the group said in an e-mail to supporters. “That's why our opponents are resorting to special interest money and television ads to strong-arm lawmakers into thinking the people of Indiana actually want this harmful language in our Constitution.”

Indiana lawmakers returned to work on Monday and are shortly expected to take up a needed second vote on HJR-6 before heading to voters in November.
