An Associated Press-National Constitution Center Poll conducted last August found 52 percent of Americans saying the federal government should give legal recognition to marriages between couples of the same sex, while 46 percent said it should not.

In polling by ABC News and The Washington Post, support for the legalization of gay marriage climbed from 37 percent in 2003 to 47 percent in February 2010.

A poll by the Pew Research Center for the People and the Press in September found 43 percent of those surveyed favored allowing gays and lesbians to marry legally, and 47 percent opposed it — the highest support for same-sex marriage in the center’s polling back to 1996. The poll showed wide partisan divisions: 55 percent of Democrats and 46 percent of independents favored same-sex marriage, but only 21 percent of Republicans.
