Yesterday on CNN Campbell Brown harshly criticized the McCain campaign for sheltering Sarah Palin from any interaction with the media. The impetus was yesterday’s dust-up with reporters attempting to cover the vice presidential nominee’s visit to the United Nations. “I have had enough of the sexist treatment of Sarah Palin,” Brown said. “It has to end. … Tonight I call on the McCain campaign to stop treating Sarah Palin like she is a delicate flower that will wilt at any moment.”
