It wouldn't be necessary to ask them, given the amount of thought or research they've put into it. It's just another of those convenient metafictions conservatives (Michelle Malkin and Sean Hannity in particular) came up with in the hopes that it'll be Obama's Whitewater (only, you know, with actual evidence leading to impeachment and criminal proceedings). And people fall for it because they've seen The Untouchables and think, "Oh well, that's Chicago for you". Plus Daley's a Democrat who can't seem to lose, so OBVIOUSLY his secret cabal is rigging the game.
