here's what i don't quite get...

John Edwards isn't running for president and currently does not hold any public office while the media seems to be paying a lot of attention to this whole John Edwards adultery story (either that or I'm watching too much FOX) On the other hand, John McCain is running for president and does currently hold public office and yet there seems to be very little discussion of the character questions raised by McCain's treatment of his first wife.

And then on top of that you have Cindy McCain's own issues... I don't mean her drug addiction (which is basically a medical question) but stealing drugs from her own charity in order to get satisfy that addiction is a serious ethical lapse.
