President Obama and the Democratic leadership are making a critical error in embracing the Occupy Wall Street movement—and it may cost them the 2012 election.

Last week, senior White House adviser David Plouffe said that "the protests you're seeing are the same conversations people are having in living rooms and kitchens all across America. . . . People are frustrated by an economy that does not reward hard work and responsibility, where Wall Street and Main Street don't seem to play by the same set of rules." Nancy Pelosi and others have echoed the message.

Yet the Occupy Wall Street movement reflects values that are dangerously out of touch with the broad mass of the American people—and particularly with swing voters who are largely independent and have been trending away from the president since the debate over health-care reform.

The protesters have a distinct ideology and are bound by a deep commitment to radical left-wing policies. On Oct. 10 and 11, Arielle Alter Confino, a senior researcher at my polling firm, interviewed nearly 200 protesters in New York's Zuccotti Park. Our findings probably represent the first systematic random sample of Occupy Wall Street opinion.

Our research shows clearly that the movement doesn't represent unemployed America and is not ideologically diverse. Rather, it comprises an unrepresentative segment of the electorate that believes in radical redistribution of wealth, civil disobedience and, in some instances, violence. Half (52%) have participated in a political movement before, virtually all (98%) say they would support civil disobedience to achieve their goals, and nearly one-third (31%) would support violence to advance their agenda.

The vast majority of demonstrators are actually employed, and the proportion of protesters unemployed (15%) is within single digits of the national unemployment rate (9.1%).
