WASHINGTON, D.C. - A national survey indicates younger Americans are causing a shift in how the country views same-sex marriage.
The Pew Research Center poll finds acceptance of gay marriage has increased because many Americans say they now know someone who is gay or who have changed their views as they have gotten older.
The issue grabbed the national spotlight recently with the public embrace of same-sex marriage by former Secretary of State Hillary Rodham Clinton and Republican Sen. Rob Portman of Ohio.
Overall, the poll finds 49 percent of Americans favor same-sex marriage. That includes 14 percent who say they had changed their minds.
