THEY DON'T DO THAT, DO THEY?

Can anyone offer me an example of a staffer for a right-wing presidential candidate resigning in response to a campaign waged by a relatively low profile left-wing organization whose claims of offense on behalf of a large chunk of the population were repeated loudly and uncritically by the mainstream media without any substantive investigation into the nature of the organization? For that matter, can anyone think up a scenario in which such a thing credibly could take place? Can you see a Mitt Romney staffer leaving as a casualty of a campaign to off him by the Mexican American Legal Defense and Education Fund? What are the chances such a campaign would even make it into the New York Times? And if it did, wouldn't it be in an article full of right-wing Mexicans bashing MALDEF as a Democratic Party organ?
