Sarah Palin's bus tour -- if it is really a family vacation, is it a campaign finance violation?

All this John Edwards hubbub makes me wonder -- if Sarah Palin's bus tour was really a "family vacation," how is her PAC paying for it? (Answer: it is not really a "family vacation.")

One Nation:
"She is being coy about her One Nation Tour, calling it a family vacation. Mighty fancy wheels for a one week vaca. Yes, a tour bus shrink wrapped and emblazoned with your name on it, the name of the tour – who names a family vacation? – and your website address, complete with an enormous pictorial of the constitution and the Liberty Bell. Yep, that’s the way most people travel with their family for a one week sightseeing getaway. I know, that’s how we do it."
