What I mean is; she speaks to tea partiers, preaching to the choir. She writes books. Conservatives will read them liberals won’t, swing voters are generally too stupid to read. She needs to start addressing obama directly. She needs to hammer certain issues such as the healthcare bill.
In my opinion, Palin is not very effective as a criticizer.
She isn’t all that great at explaining her own positions. As you say, she aims her efforts at people who already understand her principles and values.
She is the best at energizing the people who agree with her so that they get out and do stuff.
I have no idea how she goes about reaching out to the people who don’t agree with her. She hasn’t done much of that yet. Her strength typically makes the other side hate her rather than persuading them that they ought to join her.
Maybe that’s what the book and the TV series are about.
