The Pew Research Center poll found 45 percent of adults now favor allowing gay marriage and 46 percent oppose it. Forty-five percent is the highest support Pew has found for allowing same-sex marriage since they began polling on the issue in 1996. As recently as April of 2009, Pew found only 35 percent of adults supported allowing gay marriage. Other surveys Pew conducted in 2008 and 2009 generally showed support for gay marriage in the 38-40 percent range.
Pew's report notes that support for marriage is divided geographically. Majorities in the Northeast and West support marriage rights, but only 40% in the Midwest and 34% in the South favor allowing it.
