Oregon Mayor Stripped (pun!) of Power

How come Carmen Kontur-Gronquist had to step down as mayor for posing on a firetruck in sexy underwear (years ago, before she was mayor), but everyone is ok with Arnold Swarchenegger having posed in tiny banana hammocks (years ago, before he was gover-nator)?

I cry sexism.

p.s. Damn, girl! Nice abs!
