Although McKinsey released the methodology of its ESI study early this week after heavy pressure from Democrats, those same Democrats aren't getting any quieter.

"As we learn more, it's become clear that this one flawed study from McKinsey is truly an outlier," Nancy-Ann DeParle, assistant to the president and deputy chief of staff, said in a blog post.

Democrats have consistently blasted McKinsey's survey—which claimed a third of employers will likely drop health coverage for employees due to health care reform—from the time they released the initial results. McKinsey has repeatedly conceded that the study was not intended as a predictive economic analysis, but rather as a study capturing the attitudes of employers.
