Yeah she made it clear to me that once she announced things would drastically change and she likes not being constrained at this point ...smart if you as me...
Well, if she announces, she's off Fox, contract or not. That was made clear by Roger Ailes*, head of Fox News, the other day. However, it sounds more like she's getting tired of Fox and just maybe they are constraining her and she doesn't have as much freedom to say what she wants on there. Heck, I had to watch her Iowa speech on CNN; Fox didn't cover it except for Carl Cameron giving a wrap-up interview as he would with any other person, candidate or not. They're dissing her and she doesn't get to respond on the air.
*Ailes also said Fox was going to be more "mainstream" and no more Glenn Beck-type hour shows.
