Correct. They don't follow the legal ins or outs. Kerry has said he opposes gay marriage. Plus, most folks are not single issue voters, believe it or not.
He said *personally believed* marriage to be between a man and a woman, as I recall from a dim debate, but in typical fashion, never explained whether he also believed that marriage could be between a man and a man, and a woman and a woman, and never criticized the Mass. decision or any of its progeny.
John Kerry is about as against same sex marriage as I am against winning a lottery.
