The Supreme Court won't rule until June, but gay-marriage advocates said the justices' decision to tackle the issue has already helped them win a victory in the court of public opinion. "The more and more the country talks about this issue, the more and more people come to our side," Michael Cole-Schwartz of the Human Rights Campaign said Wednesday after the high court heard two days of arguments on same-sex marriage cases. A wave of senators — from Ohio Republican Rob Portman to Virginia Democrat Mark Warner — publicly backed marriage equality in the days before this week's back-to-back hearings. Surveys show Americans increasingly support legalizing same-sex marriage. A Washington Post/ABC News poll found 58 percent of people in this country think it should be legal for gays and lesbians to tie the knot.
