The knock on ACSH comes primarily from partisan groups like Mother Jones. A disgruntled employee who thought he should run the company quit and took their donor list and Mother Jones crafted a causalation paper saying that they were being paid to be shills. See, they wrote about this and a company in that business gave them money.
Science 2.0 has a lot more traffic than ACSH and I have never had anyone call me up and tell me they will pay money if we write about some cancer-causing death product, so that doesn't pass the smell test. A corporate toadie who is an intellectual shill for every weird progressive position - anti-science across the board - thinking they are somehow more ethical than anyone else is funny. They are only hired because the company knows what they are going to write about. Likewise, if everyone is hammering on Dow Monsanto ADM (insert the Evil Corporation Of The Week here) and one group is not, of course they will get money to keep doing what they are doing. Mother Jones operates the exact same way.
Hayworth has no baggage. She is an M.D. with a degree in biology, a former member of Congress, she is already rich, so she can't be bought off, and she has been lauded by Sierra Club, Wilderness Society and the Humane Society of the United States. The only thing partisan groups can complain about is that she is a Republican, if she were a female Democrat with those credentials they'd have a cover story on her.
