Anytime sex leeches into money, you have problems. That's why John Edwards has a grand jury on his butt, seemingly looking into whether the money his late presidential campaign's finance chair gave to his mistress violated campaign finance laws. This is what took the Ensign story from bad judgment to a killer. Sanford's problems were made much worse because of his weird lying and absence from his job, yes, but also the use of state funds. An Elliott Spitzer comeback to public life--it's already begun with his writing--is much more plausible because the wealthy heir to a real estate fortune paid for hookers out of his own pocket. This is a tolerant country. John McCain's admitted failings from his first marriage didn't hurt his chances at the GOP presidential nomination. Bill Clinton came back from impeachment. People understand failings in their pols and movie stars maybe because they see it in themselves. But the appearance of the abuse of public funds remains, I think, the sin that's much harder to forgive.
