We may lose AZ though.
It would be an acceptable loss.
I don’t think we should hope for McCain cratering as that could adversely affect down ticket races, including some very conservative candidates who won house races such as Jesse Kelly in Arizona 8. I don’t like McCain as I don’t trust him given his past (although if he maintains his grudge against Obama, he might not be too bad), but I don’t dislike him enough to hope he loses and drags people down like Jesse Kelly.
