For many years the combined forces of the far right and the Republican Party have sought to ruin ACORN, the largest organization of poor and working families in America. Owing to the idiocy of a few ACORN employees, notoriously caught in a videotape “sting“ sponsored by a conservative Web site and publicized by Fox News, that campaign has scored significant victories on Capitol Hill and in the media.

Both the Senate and the House have voted over the past few days to curtail any federal funding of ACORN’s activities. While that congressional action probably won’t destroy the group, whose funding does not mainly depend on government largesse, the ban inflicts severe damage on its reputation.

In the atmosphere of frenzy created by the BigGovernment videos — which feature a young man and an even younger woman who pretend to be a prostitute and a pimp seeking “advice” from ACORN about starting a teenage brothel — it is hardly shocking that both Democrats and Republicans would put as much distance as possible between themselves and the sleazy outfit depicted on-screen.

Like so many conservative attacks, the crusade against ACORN has been highly exaggerated and even falsified to create a demonic image that bears little resemblance to the real organization. Working in the nation’s poorest places, and hiring the people who live there, ACORN is not immune to the pathologies that can afflict institutions in those communities. As a large nonprofit handling many millions of dollars, it has suffered from mismanagement at the top as well — although there is nothing unique in that, either.

Yet ACORN’s troubles should be considered in the context of a history of honorable service to the dispossessed and impoverished. No doubt it was fun to dupe a few morons into providing tax advice to a “pimp and ho,” but what ACORN actually does, every day, is help struggling families with the Earned Income Tax Credit (whose benefits were expanded by both Ronald Reagan and Bill Clinton). And while the idea of getting housing assistance for a brothel was clever, what ACORN really does, every day, is help those same working families avoid foreclosure and stay in their homes.

Perhaps the congressional investigation now demanded by some Republican politicians would be a useful exercise, if conducted impartially. A fair investigation might begin to dispel some of the wild mythology promoted by right-wing media outlets.

Among the most popular canards on the right, repeated constantly by conservative pundits and politicians, is that ACORN has been found guilty of engaging in deliberate voter fraud, using federal funds. In reality, ACORN has registered close to 2 million low-income citizens across the country over the past five years — a laudable record with a very low incidence of fraud of any kind.

To claim that the stupid behavior of a half-dozen employees should discredit a national group with offices in more than 75 cities staffed by many thousands of employees and volunteers is like saying that Mark Sanford or John Ensign have discredited every Republican governor or senator. Indeed, the indignation of the congressional Republicans screaming about ACORN and the phony streetwalker is diluted by the presence of at least two confirmed prostitution clients — Rep. Ken Calvert and Sen. David Vitter — in their midst. Neither of those right-wing johns has been even mildly chastised by their moralistic peers. Nobody is cutting off their federal funding.

ACORN has pledged to institute reforms, with the appointment of a distinguished outside panel to oversee that process. Let us hope they succeed. Even now they seem far more likely to improve their performance — and to be more sincere in their intentions -- than the Washington hypocrites who are trying to destroy them.
