WASHINGTON — President Barack Obama's endorsement of gay marriage appears to have made Americans on both sides of the issue even more entrenched in their positions, firing up his young, liberal backers and intensifying opposition from Republicans and conservatives, according to a new poll.

Overall, his announcement last month that he supported gay marriage did little to shift the nation's views on the subject, with the country remaining evenly divided on it, the Associated Press-GfK survey found. And people still seem to favor him over Republican presidential rival Mitt Romney when it comes to handling social issues.

Even so, the poll, out Friday, found stronger approval from Democrats and liberals for the way he's handled gay marriage over the last year and deeper discontent over that performance from the other side.

In the poll, 42 percent of respondents oppose gay marriage, 40 percent support it and 15 percent are neutral. Last August, the country was similarly divided over whether same-sex couples should be allowed to be legally married in their state, with 45 percent opposing, 42 percent favoring and 10 percent neutral.

The country's divisions – and conflictions – are clear in the voices of Americans.

"Marriage is a marriage, and it's between a man and a woman," said John Von Sneidern, a 76-year-old Republican from Fairfield, Conn., before pausing. "But on the other side of that, there are a lot of gay couples who are responsible and dedicated to each other and deserve a lot of the benefits of marriage."

The issue, however, won't shape his vote. He plans to vote on the economy and support Romney because of his private-sector experience.

Katherine Galdarisi, a 67-year-old Democrat from Sacramento, Calif., backed Republican John McCain four years ago but plans to vote for Obama this time. That's partly because she faults Republicans for not working with the president on issues voters care about, saying: "They fight him every step of the way and talk about things that don't matter, like gay marriage."

"It's none of anybody's business," Galdarisi said. "It doesn't affect me in the least."

For years, Obama faced pressure from the left to announce his support for gay marriage, and he spent a chunk of his presidency signaling that he would do just that by saying that he was "evolving" on the issue.

While the economy continues to dominate the presidential race, Obama's team was mindful that anything – including social issues like gay marriage – could shift the balance in a contest that appears close five months from the election. Even so, Obama announced his reversal and risked turning off some conservative, moderate and independent voters across the nation and in states like Virginia and North Carolina that hadn't voted for a Democratic presidential candidate in decades until Obama won them four years ago.

But the AP-GfK poll suggests that voters, at least nationally, didn't flee the president.

When asked which candidate Americans trust to do a better job of handling social issues such as abortion and same-sex marriage, there was little change from a poll taken about a week before Obama's May 9 announcement; 52 percent now side with Obama, compared with 36 percent for Romney.

And more Democrats and liberals said they strongly approved of the president's handling of gay marriage than they did in August; 41 percent of Democrats now say that, compared with 26 percent then, and 48 percent of liberals have that view, up from 28 percent almost a year ago.

But his announcement may have fired up the right against him. More Republicans and conservatives said they strongly disapproved of his handling of the issue now than before; 53 percent of Republicans said that, compared with 45 percent in August, and 52 percent of conservatives say as much now, up from 43 percent back then.

The issue could compel more conservatives to turn out to vote against Obama.

Self-described social conservative Bethel Hissom of Knoxville, Tenn., is among those who plan to back Romney and don't support allowing gays to wed.

"It's not marriage," the 65-year-old retired speech therapist said. Of Obama's position, she said: "It will probably help his chances at being re-elected. It will get the gay population in favor of that and that could swing votes to his favor. But it is not marriage."

Obama's announcement clearly affected some – and in personal ways.

Trevor Rzucidlo, a 22-year-old who graduated last month from the University of Connecticut, had a roommate who is gay, and said that hearing the president speak out in support of someone he cared about "was huge."

"My peers are just way more chilled out than older people are," said Rzucidlo, who considers himself an independent and plans to vote for Obama. "They're less concerned with how other people live their lives."

Indeed, support for gay marriage remains a more popular position with younger voters: 50 percent of people under age 35 said they would favor allowing same-sex couples to be legally married in their state, compared with 36 percent of those ages 35 and up.

Among those under 35, overall approval of the president's handling of same-sex marriage has held steady, but those who back him do so more strongly now. His "strong" approval numbers have doubled, jumping from 17 percent last August to 34 percent in the AP-GfK survey.

The Associated Press-GfK Poll was conducted June 14-18, 2012, by GfK Roper Public Affairs and Corporate Communications. It involved landline and cellphone interviews with 1,007 adults nationwide, including 878 registered voters. Results for the full sample have a margin of sampling error of plus or minus 4.0 percentage points and for registered voters it is 4.2 points.

  • Michael Bloomberg

    "This is a major turning point in the history of American civil rights," said New York City mayor Michael Bloomberg. "No American president has ever supported a major expansion of civil rights that has not ultimately been adopted by the American people - and I have no doubt that this will be no exception. The march of freedom that has sustained our country since the Revolution of 1776 continues, and no matter what setbacks may occur in a given state, freedom will triumph over fear and equality will prevail over exclusion. Today's announcement is a testament to the President's convictions, and it builds on the courageous stands that so many Americans have taken over the years on behalf of equal rights for gay and lesbian Americans, stretching back to the Stonewall Inn in Greenwich Village."

  • Jerrold Nadler

    "I applaud President Obama for announcing his support for marriage equality today," said Rep. Jerrold Nadler (D-N.Y.) "For the first time in this nation's history, a sitting president has shown the courage and leadership to stand up for all American families by pledging to support the fundamental right of every person to marry the person they love, and to have that marriage fully respected. I commend President Obama for this brave and honest step. Those who seek to politicize civil rights for personal or political gain will certainly attack him, but the course toward marriage equality and justice is the correct and inevitable path."

  • Brad Lander

  • Fred Karger

    "I'm thrilled!" longshot GOP presidential candidate Fred Karger told HuffPost, referring to Obama's embrace of marriage equality. Karger is the first openly gay Republican or Democrat to run for president. "The Karger pressure has worked," he joked. "Particularly after the defeat in North Carolina, we welcome him to the full equality position."

  • Chellie Pingree

  • Mike Huckabee

    "Barack Obama just announced he supports same-sex marriage," Mike Huckabee wrote in a fundraising appeal to supporters. "Nancy Pelosi immediately jumped on the announcement and emailed Democrat activists nationwide promising to continue their fight. This is going to be a defining issue this election. Obama, Pelosi and the Democrats have been a complete failure on economic issues so now they are going to focus on issues that will rile up their base. Well, Mr. President it's going to rile up our folks also. Men and women who support traditional marriage."

  • Rep. Bill Taylor

  • Deval Patrick

  • Frank Lautenberg

    "President Obama's support for marriage equality marks an important moment for civil rights in America," said Senator Frank R. Lautenberg (D-NJ), who co-sponsored legislation that would repeal the Defense of Marriage Act (DOMA). "We simply can not treat same sex couples as second-class citizens in our country. Marriage equality is one of the most significant civil rights battles of our time and is critical to guaranteeing the equal protection under the law promised to every American in the Constitution. The President's support for marriage equality should inspire Congress, Governors and state legislatures to advance civil rights for all Americans."

  • Allen West

  • Ann McLane Kuster

  • Sen. Patrick Leahy

  • Peter Welch

    "This is an historic moment and I applaud the President for his decision and courage," Rep. Peter Welch (D-Vt.) said. "One of the greatest and most liberating human emotions is acceptance. And what the President did today was accept that the quality of love two people share is more important than their gender. The President's decision required him look within and engage his heart. It is truly wonderful and welcome news."

    "As an early and strong proponent of Marriage Equality, I am very happy that President Obama has made this announcement," said Rep. Steve Rothman (D-N.J.)

This is an important step in our country's march toward achieving true justice and equality for all."

  • Chuck Schumer

  • JackieForNH

  • Howard Dean

    "President Obama's public support for marriage equality is an historic affirmation of the fundamental American value of equal rights for all," said Howard Dean. "Having signed the nation's first law allowing Civil Unions as Governor of Vermont, I'm also proud to see our president affirm the belief that I and so many other Americans hold: loving and committed couples should have the same benefits that are extended through marriage. Marriage equality is a right and a benefit to all families."
