Glass houses are rarely bulletproof

Could someone please explain to me how an elected official who has founded his public persona on fighting corruption (and, ironically, busting prostitution rings in NYC) gets caught hiring a prostitute while in office and ALREADY under scrutiny?! [Never mind it was the day before Valentine's Day - try keeping it in your pants and renting some porn, buddy. Maybe send your gorgeous wife some flowers.] Seriously? Seriously. The guy's got a beautiful wife and three daughters, and he goes and does this? He's not some George W. Bush dipshit halfwit in need of a personal assistant to remind him to zip his fly - Spitzer has been gunning for the White House for quite some time, he's smart, and he's ruthless. This isn't something that was hiding in his closet either - something that happened 20 years ago that could be brushed off. It happened a month ago! Yeah, he's had a rough year, but for a guy who knows the processes, know what a federal investigation looks like, and knows what goes on in politics, wouldn't you think this could be the absolute dumbest thing he could do? As far as I'm concerned, there's only one possible explanation: extreme mental illness. Wait, there's one more: he actually was tired of being governor, and decided he'd rather resign in disgrace to become a full time stay-at-home dad.
