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. …

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%). …

What binds a large majority of the protesters together—regardless of age, socioeconomic status or education—is 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. …

Thus Occupy Wall Street is a group of engaged progressives who are disillusioned with the capitalist system and have a distinct activist orientation. Among the general public, by contrast, 41% of Americans self-identify as conservative, 36% as moderate, and only 21% as liberal. That’s why the Obama-Pelosi embrace of the movement could prove catastrophic for their party. …

Today, having abandoned any effort to work with the congressional super committee to craft a bipartisan agreement on deficit reduction, President Obama has thrown in with those who support his desire to tax oil companies and the rich, rather than appeal to independent and self-described moderate swing voters who want smaller government and lower taxes, not additional stimulus or interference in the private sector.

Rather than embracing huge new spending programs and tax increases, plus increasingly radical and potentially violent activists, the Democrats should instead build a bridge to the much more numerous independents and moderates in the center by opposing bailouts and broad-based tax increases.

Put simply, Democrats need to say they are with voters in the middle who want cooperation, conciliation and lower taxes. And they should work particularly hard to contrast their rhetoric with the extremes advocated by the Occupy Wall Street crowd.
