Larry Flynt’s offering $1 million to anyone with proof that they conducted an illicit affair with a member of congress or other high government official. My guess is that if you’ve got a genuinely compromising story, blackmail is probably more lucrative since these people tend to be rich (not that the government salaries are all that high, but the jobs tend to be filled by rich people) and certainly to have rich and powerful friends.

Indeed, I suspect that explicit blackmail is hardly necessary in these cases. Any idiot can see that it’s important to keep one’s former companions in such endeavors happy, and having a congressman consider himself to be in your debt is a solid commodity.
