All sorts of trading strategies you could try out on a full, in-advance data feed, though.
Only follow the trades of those in leadership, give special attention to transactions involving defense contractors by members of the Committee on Armed Services, etc.
I don't doubt that Congress has its share of confident morons to skew the numbers downwards, but you might be able to identify people who somehow manage to make better moves.
