OT: I was just reading about Palin’s little bus tour, and a thought occurred to me.

From all indications, the tab for this junket/family vacation/whatever is being picked up by SarahPac, her political action committee.

But didn’t Christine O’Donnell catch some flack for spending campaign contributions on personal expenses at some point.

So… what’s the dif? Why would O’Donnell get into trouble for spending campaign contributions, while Palin tricks out her bus with the the trappings of a campaign vehicle - for what she’s claiming is an innocent family vacation?
