She made one appearance with him, and made one radio spot. I suspect it was in return for some promise from him that he would start acting like a conservative if he won.
If you watched that appearance with McCain and Cindy, you would have seen Cindy McCain with a barely restrained nasty disposition toward Palin; for what, we can only guess. The McBrat's attacks against Palin have been non-stop since then.
Whatever the deal was, Sarah has kept her part of the bargain, and has said nothing against McCain publicly.
No, she made multiple documented appearances with him, including at a rally, a fundraiser, and a food event.
She also was plastered all over his campaign Web site.
Oh, and she wrote a disgusting, sycophantic op-ed for him that was published in The Arizona Republic.
