"Having Palin on the show would be a conflict of interest," said Elwood Watson, a professor of history and African-American studies at East Tennessee State University and co-author of "The Oprah Phenomenon."
"She's made up her mind, and she's not going to sway from it," said Watson, when asked whether it would be plausible for Winfrey to simultaneously support Obama and interview Palin on her show, which could be interpreted as an endorsement. "How can you endorse two people?"
With almost 1,000 comments on her community message board dedicated to a possible Palin interview, Winfrey is already garnering strong reaction among her fans -- both those who are pleased with her decision and those who are not, such as Grossman-Green.
"I'm actually pretty angry with her right now because of this," she said. "I don't think I will be a gung-ho supporter right now.
"I'd think twice about switching her on or even buying her magazine."
