As I pointed out in my earlier post, she might have been caught off guard and just gave a “nice” answer. We don't know if she is going to campaign for McCain, but you must feel good tearing her apart! The email I posted indicates she is going to be campaigning for conservatives. Perhaps if you cared to read my post you would've known this.
That's politics for you. If she disparages McCain, it's a story. If she says nothing, it's a story. And if she just says something nice, it's a story. Some people are impossible to please - it speaks volumes about them, and less about Sarah Palin.
Also, if she takes the nomination, she will need support from the center (actually center/left with McCain) and she's smart to keep that relationship as good as possible.
