Azizi, this was my source about the Culinary Union: A google hit for "Nevada Primary" hours, which i was trying to check.

"Top of the Ticket: Los Angeles Times: Breaking News: Big Nevada... the culinary workers have pulled their Obama endorsement, the union will be neutral in the Nevada Primary (source: Tim Russert on MSNBC),...

A blog on withdrawal is there, but the other blogs seem to contradict.
Russert is director and moderator of "Meet the Press." My wife always watches and recalls no such statement on his program. It seems that a blog about his program, sent to the LA Times, was incorrect; he seems to have been no such statement.

Looking at the LA Times, today, as you say, they carried the story about a Federal Judge ruling that the special caucuses were legal, so the State Supreme Court was overruled.
