A lawsuit may be filed challenging the legitimacy of the nine at-large caucus precincts local casinos have established for their workers, columnist Jon Ralston reports in his Web newsletter, RalstonFlash.
It's unclear who is considering filing the suit.
Consideration of a lawsuit comes just two days after the presumably powerful Culinary Union endorsed Illinois Sen. Barack Obama over his chief rival, New York Sen. Hillary Clinton.
Ralston predicts the union would blame Team Clinton for a suit, because it could undercut its influence: "You can be sure Clinton, who has criticized the caucus process for disenfranchising voters, would not want to be seen as being behind a lawsuit that might be seen as doing just that."
The lawsuit could be founded on the possibility that the casino precincts would get a disproportionate number of delegates, Ralston reports.
