Because she’s kept mum about any possible Presidential bid.
I think it’s good that she is not talking about a presidential bid, but it would be good if she could find more avenues to get her message directly to the public about the important issues. Facebook, twitter, and the book are great, but unless people are already fans, I don’t think she will connect with them by those means. Hopefully, she will make the rounds on talk radio to promote the book, I think that it would be good exposure.
