Well, some of them are almost certainly on Disney's payroll.
Kevin was a special case. He was actually a conservative blogger. Had his own site. Kind of made a stir when he posted an open letter to Sarah Palin in which he pretended to be part of a coffee club for the elderly. That was the birth of the Patty Melt personae. In this particular post, he claimed that (s)he had long been a supporter of Hilary Clinton. She claimed to have made Clinton-themed ornaments every Christmas. But now she realized that only Palin could save the country.
Here's a link to the post. It was typical of his/her posting style. Lots of down home stories about her bumbling husband eating all the Christmas cookies and getting in the way. Now imagine that but instead of the pro-Palin sentiment, a bunch of Disney PR.
It was beautiful, I tell you.
