Under fire from Democrats in Congress, consulting firm McKinsey & Co. today released its methodology for a controversial survey that found as many as 30% of employers might drop health insurance after the new health law takes effect in 2014. But the hot water McKinsey's in doesn't seem to be cooling off. From the start, the survey raised eyebrows because its findings were so at odds with other studies that predicted far fewer employers would drop insurance for their workers. McKinsey acknowledged in its original article about employers' possible reaction to the law's implementation that "our survey educated respondents about its implications for their companies and employees before they were asked about post 2014 strategies." What that "education" was, however, was unknown. Until now, that is.
