Poll: Most Oppose Same-Sex Marriage

Sept. 22 -- A majority of Americans oppose allowing homosexual couples to marry legally, but most also say it's not worth amending the U.S. Constitution to ban such unions, an ABCNEWS poll has found.

In the poll, 37 percent of Americans say same-sex marriages should be legal, while 55 percent say they should be illegal. But when opponents are asked if it's worth amending the Constitution to ban such marriages, six in 10 of them say it's not.

As a net total of the population, this poll finds 20 percent of Americans favor a constitutional ban on gay marriages; 33 percent oppose such marriages but wouldn't amend the Constitution; and 37 percent would make them legal.

Other polls have found much more support for a constitutional amendment, for two possible reasons. Some pose the issue in a single question, conflating views on same-sex marriage with views on an amendment to ban them. This poll asks about the two issues separately. Also, this poll asks if it's worth amending the Constitution, inviting consideration of the amendment process.

In July, President Bush said marriage should be between a man and a woman, and "we ought to codify that one way or the other." A constitutional amendment to define marriage as such has been proposed in Congress, and Senate Majority Leader Bill Frist, R-Tenn., has said he would support it.

Breakdown by Groups

Age plays a large role in views on same-sex marriages. A slight majority of people age 18-34 think homosexual marriage should be legal; that dives to 20 percent among those age 65 and older. Nevertheless, only 23 percent of older Americans who oppose such marriages say it's worth amending the Constitution to do so. Among the smaller group of young adults who oppose gay marriage, more — 47 percent — favor a constitutional amendment.

Men and women are similar in their opposition to same-sex marriage and amending the Constitution to make it illegal, but marital status and partisanship come into play. Forty-eight percent of people who are not married say homosexual marriages should be legal, compared with 28 percent of married people.
