She was on meet the press to talk about her book a few months ago. She seemed much more reasonable and thoughtful than I’d seen her either on her show (admittedly an infrequent occurrence) or when she has been on panel discussions.
I think she knows she’s playing a role when on MSNBC or when she’s part of the MTP panel, and plays up to that.
More like she knows how few people actually watch her usual tripe, not enough to sell any big number of books, so she is actually playing the role on MTP in order to fool people to buy her book.
