"She does not in any way challenge the traditional conceptions of men and women that are present among conservative evangelicals. She is a mother of five, she talks about God as having a plan for people's lives," said David Domke, a professor of communication at the University of Washington in Seattle.
Domke has his own axe to grind. He's hardly an unbiased observer, and can be expected not to find anything novel or positive in Palin's candidacy. It's strange that a professor of communications doesn't see how new messengers can make something new of an established message, but Domke's more of an advocate than an analyst.
