DES MOINES, Iowa (AP) -- Republican presidential contender Mitt Romney is launching a radio ad touting the strength of his opposition to gay marriage.
Romney, who has come under criticism from conservatives for his past support of some gay rights issues, says he is the only major GOP candidate backing a constitutional amendment to ban same-sex marriage.
''Not all Republican candidates agree, but defending marriage is the right thing to do,'' Romney says in the 60-second spot to begin airing Wednesday.
The ad is meant to set him apart from Fred Thompson, John McCain and Rudy Giuliani in the minds of conservative voters.
