THE SUBSTANCE ABUSE DODGE. As Bob Packwood discovered a few years back, now that substance abuse is (correctly) viewed as an illness rather than a sign of moral degeneracy, one can blame one's actual moral degenaracy on substance abuse to soften a public fall from grace. Not any old substance will do, mind you: crack might turn off suburbanites, heroin might evoke the specter of AIDS, and coke might seem too rockstarrish. Plus, then you're admitting to breaking the law. Alcohol, on the other hand, has the middle-American acceptability (and legality) to strike the right balance (provided that plying your under-age pages with alcohol wasn't part of your attempts to seduce them).
Thus it is no surprise that Mark Foley, after switching from denying his taste for 16-year-old underlings to admitting to them, has found the true culprit in a bottle. I guess drunk IMing is the new drunk dialing.
