But perhaps the public has reached a turning point.
A CNN poll this month found that a narrow majority of Americans supported same-sex marriage — the first poll to find majority support. Other poll results did not go that far, but still, on average, showed that support for gay marriage had risen to 45 percent or more (with the rest either opposed or undecided).
That’s a big change from 1996, when Congress passed the Defense of Marriage Act. At that time, only 25 percent of Americans said that gay and lesbian couples should have the right to marry, according to an average of national polls.
