George Will of ABC News says the opposition to gay marriage in the United States is slowly but quite literally dying; it's primarily older residents, he told This Week.
As the Supreme Court prepares to take up two landmark cases on same-sex marriage, Will said yesterday that it's clear where public opinion is headed.
"There is something like an emerging consensus," the conservative writer said, noting voters in three states recently endorsed same-sex marriage initiatives.
"Quite literally, the opposition to gay marriage is dying. It's old people."
Democratic strategist and former Bill Clinton campaign manager James Carville agreed the 2012 election marked a "profound" shift on the controversial issue.
On the table before the SCOTUS is a case challenging Proposition 8, the hot-button 2008 California ballot measure restricting marriage to opposite-sex couples.
That measure passed, thus banning gay marriage in California; the state's Supreme Court overturned the measure, however, declaring it unconstitutional.
The Court will also hear a challenge to a provision of the federal Defense of Marriage Act (DOMA), which defines marriage as between a man and a woman.
Currently, gay marriage is legal in just nine states and in the District of Columbia - but polls suggest support is growing, with a majority or close to it in support.
A recent ABC News-Washington Post poll found 51 percent of Americans support gay marriage, while a recent Pew poll shows national support at 48 percent.
That's up from 35 percent in 2001.
"To me, the consensus has already emerged," said ABC News' Matthew Dowd.
"It's just a question of … is the Supreme Court going to catch up and follow that wind of the pack, or get ahead of it or put a block in the path of it?"
