The Occupy Wall Street demonstrations garnered reactions of both praise and criticism from organizations and public figures in many parts of the world. Over time, a long list of notable people from a range of backgrounds began and continue to lend their support or make reference to the Occupy movement in general.

Domestic political responses have been both positive and critical, from the President of the United States to the 2012 presidential candidates.

International responses have come from the Egyptian protesters of Tahrir Square, Cardinal Peter Turkson, the Chinese state news agency (Xinhua), Indian Prime Minister Manmohan Singh, and many others. Most international responses have been supportive of the movement, while some, such as former United Kingdom Prime Minister Tony Blair have criticized it.

Public opinion National polls from October to December 2011 were mixed, with agreement/approval ratings for Occupy Wall Street varying from 59% to 22%. On December 19, MSNBC reported a study which showed small-business owners "are almost evenly split on whether they support the protest movement." Among the general public, opinions of OWS have varied over time, and there are contradictions between the data collected by various polling agencies.

September–October 2011 An NBC/Wall Street Journal survey released October 12 found that 37 percent of respondents "tend to support" the occupy movement, while 18 percent "tend to oppose" it. An October 13 survey by TIME magazine found that 54 percent of Americans have a favorable impression of the protests, while 23 percent have a negative impression. An October 18 Gallup poll found that 22 percent of Americans agree with the protest's goals, while 15 percent disapprove and the remaining 61% say they don't know enough to decide. Gallup found that Democrats, Independents and Republicans all follow the news about OWS in equal numbers, and those who closely followed OWS were also those who were more likely to approve of its goals and methods. An October CBS News/New York Times polls found 43% of Americans agree with Occupy Wall Street while 27% disagree. An October Rasmussen poll found an almost even split, shows that 33 percent of Americans have a favorable view, while 27 percent are unfavorable and 40 percent have no opinion. A Pew poll taken October 20–23 had similar findings, with 39% supporting "the Occupy Wall Street movement," while 35% opposed.Pew Research Center, "Public Divided Over Occupy Wall Street Movement ," October 24, 2011. An October United Technologies/National Journal Congressional poll found that 59 percent of Americans agree with the movement while 31 percent disagree.

An October Quinnipiac University poll of New York City voters found that 67 percent of New Yorkers approved of the movement with 23 percent disapproving. The results also found 87 percent of New Yorkers find it OK that they are protesting. Despite media criticism that the protesters views are incoherent, the poll also found that 72 percent of New York City voters understand their views.

November–December 2011 A NY1-Marist Poll released show of November 1ed 44 percent of New York voters supported the Occupy Wall Street movement, while only 21 percent supported the Tea Party. A survey of roughly 1,000 adults conducted from November 10 to 14 found that majorities of nearly identical size felt that Occupy Wall Street, and the Tea Party, respectively, did not share their values. A November 3 poll done by the Quinnipiac University Polling Institute found that 30 percent of American voters have a favorable view of the protests, while 39 percent do not. The same poll found that among independent voters, 29 percent have a favorable view opposed to 42 percent who have an unfavorable view, while 45% of Democrats have a favorable view opposed to 19% who have an unfavorable view. A Pew Research Center poll, released December 15, 2011, found that nearly three months after the start of OWS, 44% support the Occupy Wall Street movement and 35% oppose it. Americans overwhelmingly agree with the concerns raised by the movement, but more disapprove of the tactics used than approve.Pew Research Center, "Frustration with Congress Could Hurt Republican Incumbents " December 15, 2011. Section Two: "Occupy Wall Street and Inequality," page 11

According to a November Wall Street Journal article, the age group that most strongly supported OWS were 50 to 64, and OWS had the strongest support among those making $50,000 to $70,000 a year, rather than under $30,000, with only 27% of people making over $75,000 a year backing the movement. Managers and other professionals supported the movement more than blue-collar workers, and men over 50 showed the strongest support.Populist Movements Rooted in Same Soil The Wall Street Journal By GERALD F. SEIB, November 15, 2011 "You know how they have been pigeonholed: The tea-party movement is nothing but a collection of right-wing, under-educated rubes and radicals, while the Occupy Wall Street movement attracts only young, scruffy, unemployed left-wing zealots." These findings were contradicted by a December Pew Poll, which found opposition to OWS "higher in the older and affluent" while those making under $75,000 a year and those under 29 were the most supportive. The Pew poll (published Dec. 15) also found more support than opposition in Democrats (60/21) and Independents (46/34), and more opposition than support in Republicans (21/59).Pew Research Center, "Frustration with Congress Could Hurt Republican Incumbents " December 15, 2011. Section Two: "Occupy Wall Street and Inequality," page 12

In an opinion piece in the Wall Street Journal, pollster Douglas Schoen wrote that polling of the protesters revealed "values that are dangerously out of touch with the broad mass of the American people" and have "a deep commitment to left-wing policies: opposition to free-market capitalism and support for radical redistribution of wealth, intense regulation of the private sector, and protectionist policies to keep American jobs from going overseas", and that politicians who support them will be hurt in the 2012 elections. Journalist David Weigel responded in an opinion piece published on Slate characterizing Schoen's opinion piece as "a dishonest column full of claims that couldn't be backed up by his own research", while Washington Monthly lead blogger Steve Benen wrote an opinion piece accusing Schoen of political spin in his analysis and referring to Schoen, a frequent contributor to Fox News, as "the quintessential 'Fox News Democrat'".

Political response

The White House During an October 6 news conference, President Barack Obama said, "I think it expresses the frustrations the American people feel, that we had the biggest financial crisis since the Great Depression, huge collateral damage all throughout the country ... and yet you're still seeing some of the same folks who acted irresponsibly trying to fight efforts to crack down on the abusive practices that got us into this in the first place." When Jake Tapper of ABC News pushed Obama to explain the fact that his administration hasn't prosecuted any Wall Street executives who didn't play by the rules, he replied, "One of the biggest problems about the collapse of Lehman's and the subsequent financial crisis and the whole subprime lending fiasco is that a lot of that stuff wasn't necessarily illegal; it was just immoral or inappropriate or reckless." On October 18, when interviewed by ABC news, he said "in some ways, they're not that different from some of the protests that we saw coming from the Tea Party. Both on the left and the right, I think people feel separated from their government. They feel that their institutions aren't looking out for them."

On November 22, President Barack Obama was interrupted at a speech in New Hampshire by a group of Occupy Wall Street protesters who attempted to chant slogans during the speech; the protesters later delivered a paper message to the press, which read, "Mr. President: Over 4,000 peaceful protesters have been arrested while bankers continue to destroy the economy. You must stop the assault on our First Amendment rights. Your silence sends a message that police brutality is acceptable. Banks got bailed out. We got sold out." The crowd quickly drowned the protesters out with chants of "Obama!" Obama then responded, "I appreciate you guys making your point. Let me go ahead and make mine." Later in the speech, Obama said, "Families like yours, young people like the ones here today — including the ones who were just chanting at me — you're the reason that I ran for office in the first place."

Vice President Joe Biden likened the protest to the Tea Party's similar anger at the banks, saying, "Look, guys, the bargain is not on the level anymore in the minds of the vast majority of the American (people). The middle class has been screwed."

Congress

House Democratic Leader Rep. Nancy Pelosi said she supports the growing nationwide Occupy Wall Street movement. Pelosi said she includes herself in the group of Americans dissatisfied with Congress and stated, "I support the message to the establishment, whether it's Wall Street or the political establishment and the rest, that change has to happen. We cannot continue in a way (that) is not relevant to their lives."

Independent Senator Bernie Sanders of Vermont, who caucuses with the Democratic Party, appeared on Countdown with Keith Olbermann and supported the protests saying, "We desperately need a coming together of working people to stand up to Wall Street. We need to rebuild the middle-class in this country and you guys can't have it all."

House Majority Leader Eric Cantor (R-Va), in a speech to a Values Voter Summit, characterized the movement as "growing mobs" and said that Obama's "failed policies" and rhetoric "condon[ing] the pitting of Americans against Americans" were to blame. In response, White House Press Secretary Jay Carney accused Cantor of "unbound" hypocrisy, given the Majority Leader's support of the Tea Party protests, adding, "I don't understand why one man's mob is another man's democracy." Carney characterized both movements as examples of American democratic traditions.

The Democratic co-chairs of the Congressional Progressive Caucus, Representatives Raúl Grijalva and Keith Ellison, announced their solidarity with the movement on October 4."CPC Co-Chairs Applaud Occupy Wall Street Movement" . Congressional Progressive Caucus. October 4, 2011. The Democratic Congressional Campaign Committee is asking for 100,000 names on its website which will subsequently be added to 100,000 letters to Speaker of the House John Boehner and House Majority Leader Eric Cantor, expressing support for the Occupy Wall Street protesters, the middle class, and opposition to tax loopholes for millionaires and big oil.

2012 presidential candidates 2012 Republican presidential candidate Mitt Romney said that while there were "bad actors" that needed to be "found and plucked out", he believes that to aim at one industry or region of America is a mistake and views encouraging the Occupy Wall Street protests as "dangerous" and inciting "class warfare". Romney later expressed sympathy for the movement, saying, "I look at what's happening on Wall Street and my view is, boy, I understand how those people feel."

Former Governor of New Mexico and 2012 Libertarian Party presidential candidate Gary Johnson visited Occupy Wall Street in October 2011 and expressed support, stating "This country is not equal. We don't treat everyone equally. I would like to see us focus on the root cause, which is in my estimation politicians that are getting paid off. That's the corporatism and the outrage."
