Reporting the news always safer than predicting it. From the AP, last Saturday:

This time there were no tortured explanations, no heels dug in, no long, slow drip of revelation or fight for redemption. Rep. Mark Foley, R-Fla., just up and quit after his e-mails expressing undue interest in a 16-year-old male page were exposed to the nation. Less than six weeks from a tough election for Republicans who control an already ethically tainted Congress, the more common stick-it-out approach to scandal was cast aside.

"Resigning leaves your attackers nowhere to go," said Eric Dezenhall, a crisis-management consultant. "If this had dragged on, it could have sucked Republicans into the vortex of scandal."

Hmmm, is that a giant sucking sound I hear?
