Mark Morial's New Orleans may have set the high-water mark for corruption & old-time machine politics, but I haven't found enough info on the web to make a decent post about it.
Sadly, it's not new- I am re-reading The Dark Side of Camelot by Seymor Hersh, and the level of vote fraud and corruption the Kennedys pulled off- repeatedly- is astounding. And yep, the Jackal Pack press was silent then, too...
