LOWELL, Mass. – A new national UMass Lowell-Boston Herald poll finds slightly more Americans view the Occupy Wall Street movement unfavorably than favorably, while perceptions are more sharply negative about the Tea Party. Yet many Americans with positive impressions of each movement, despite ideological differences, agree that Wall Street and political action committees have too much influence on politics while people who are not wealthy have too little, the poll finds. Detailed poll results and analysis are available at www.uml.edu/polls and www.bostonherald.com.
