In the Nov. 2 elections, 11 states approved amendments to their constitutions banning same-sex marriage.
Also on Nov. 2, President Bush - who has stated publicly that he supports an amendment to the federal Constitution - won re-election by more than 3.5 million votes. Now, many across the country are wondering whether that nationwide amendment is far behind.
Thirty-six states have statutes that prohibit the practice - a ban supported by the federal Defense of Marriage Act, passed in 1996.
And aside from the 11 states that amended their constitutions Nov. 2 to include bans, five already have done so. Experts disagree on whether such an amendment could pass during Bush's second term.
Patrick Fagan, an expert in family and cultural issues at the Heritage Foundation, a conservative think tank, said it is possible that Congress could pass the amendment within the next four years.
"If (President Bush) gives real strong leadership on this, without a doubt, he can lead the country where the electorate wants him to go."
Fagan said that the issue can be framed as a battle between the American people and public officials and that the conflict is caused by judges whose views diverge from those of the general public.
"It's very clear the overwhelming majority of people want marriage protected as a fundamental institution between men and women," he said. "It's also clear that a lot of judges don't want that."
Jonathan Rauch, a writer in residence at the Brookings Institution and author of the book "Gay Marriage: Why It Is Good for Gays, Good for Straights, and Good for America," said that while he wouldn't rule out the possibility that the amendment will pass, he doesn't think it will get bipartisan support.
