Leaked, maybe, but I doubt if the DUI story had to be "found." Courthouse pols have some of the longest memories known to man. A lot of them are political obsessives whose talents didn't take them beyond local wardheeling. In a county where not much of note has happened in 200 years, you can bet your booties some of them would remember the son of a prominent family getting a DUI. You never outrun that kind of stuff in a small town.
I am still interested in this story, however, because I have trouble buying the idea that MADD marched in and sought the unsealing of old records just as a coincidence. My supposition is that a dem courthouse pol recalled the story, passed it up the chain, and the move to open the records was the result. But I've never seen this analyzed and confirmed. Does anyone here have the background?
There was a lot of investigations and research done by FReepers back when this story came out, and even more details in the months afterward. I read them with interest. You're right, there was one old wacky bird who knew of the story back from the day it occured and tried to sell it. The conspiracy part was this: How long did the Drive by Media know of it before they all ran with it the Friday before the election? Some say as much as a year!
You'll have to do a search from that time period. I don't have any links.
