There have been a lot of claims about racist signs at tea parties over the past 18 months. And clearly there have been some. I used to go to antiwar rallies, and they would have people carrying giant 10-foot banners for various communist parties, which the media would politely ignore.

Emily Ekins, a graduate student in political science who has been interning at the Cato Institute, wondered just how many such signs there might be. So, as the Washington Post reports, she decided to find out:

A new analysis of political signs displayed at a tea party rally in Washington last month reveals that the vast majority of activists expressed narrow concerns about the government’s economic and spending policies and steered clear of the racially charged anti-Obama messages that have helped define some media coverage of such events.

Emily Ekins, a graduate student at UCLA, conducted the survey at the 9/12 Taxpayer March on Washington last month by scouring the crowd, row by row and hour by hour, and taking a picture of every sign she passed.

Ekins photographed about 250 signs, and more than half of those she saw reflected a “limited government ethos,” she found — touching on such topics as the role of government, liberty, taxes, spending, deficit and concern about socialism. Examples ranged from the simple message “$top the $pending” scrawled in black-marker block letters to more elaborate drawings of bar charts, stop signs and one poster with the slogan “Socialism is Legal Theft” and a stick-figure socialist pointing a gun at the head of a taxpayer.

There were uglier messages, too — including “Obama Bin Lyin’ — Impeach Now” and “Somewhere in Kenya a Village is Missing its Idiot.” But Ekins’s analysis showed that only about a quarter of all signs reflected direct anger with Obama. Only 5 percent of the total mentioned the president’s race or religion, and slightly more than 1 percent questioned his American citizenship.

Ekins’s conclusion is not that the racially charged messages are unimportant but that media coverage of tea party rallies over the past year have focused so heavily on the more controversial signs that it has contributed to the perception that such content dominates the tea party movement more than it actually does.
