Perhaps we're reading too much into this, but Sarah Palin has turned down a number of publicity opportunities recently, and it's making us uneasy. Take, for example, a couple of weeks ago, when Palin traveled to Washington for some closed-door meetings and left the city without holding a single interview or press conference. She even told House Republicans that she couldn't speak at their winter retreat because she was "busy in Alaska," a lazy and easily disproven lie. Now, Palin has reneged on headlining the annual conference for the Conservative Political Action Committee (CPAC). Who is this suddenly, curiously, publicity-shy woman? What happened to the attention-grabbing Palin who purposely used a turkey slaughter as a backdrop for an interview? We don't know exactly what Palin is up to, but we're alarmed, and frightened.
