Obama's fallen off the wagon in the last few months. What? He's an alcoholic? A coke head? A sex addict? Nope -- that's the last two guys who have held the office he seeks. Obama's particular addiction is tobacco. According to the Obama camp, however, he's back on the wagon and chewing away at the Nicorette, but he recently admitted that he has snuck a few cigarettes here and there while on the campaign trail.
I'm certainly in no position to judge in this case, having spent plenty of time as a closet smoker myself. There is a certain amount of benign deception involved. To sneak a cigarette, one must have a willingness to create elaborate justifications for one's behavior. You have to have the ability to appear to be doing one thing (taking out the trash, looking for firewood, heading out for a meeting to discuss the latest Zogby poll) when you really are doing another (furtively hot-boxing a heater and looking for a place to stash the butt*).
In other words, it's politics.
*Geez...it's still almost like I'm talking about Clinton, isn't it?
