Despite reports that Culinary Workers Local 226 will endorse Barack Obama for president tomorrow morning (see Tim Russert’s unattributed pronouncement on the Today Show this morning), the 60,000-strong union of casino and hotel workers is still undecided.

In fact, no vote has taken place yet. That’s planned for 11 pm EST tonight when the executive committee of the union’s international parent Unite Here convenes a conference call to discuss the decision — and presumably the results of the New Hampshire primary, according to union spokeswoman Amanda Cooper.

The committee comprises 12 members, including co-presidents Bruce Raynor and John Wilhelm, who ran the Culinary Union in Las Vegas before taking his post in the international. Culinary Secretary-Treasurer D. Taylor is one of 10 executive vice presidents on the committee.

The endorsement, if one is decided, will be announced tomorrow morning at 11 a.m. at the Culinary Union’s headquarters here.

Interesting bit of hedging on the part of Unite Here: “I can’t guarantee you that they will make a decision today,” Cooper said. “I can’t predict who they will endorse or if they’ll endorse. We’ve arranged to make this announcement tomorrow to satisfy the intense curiosity.”

Raynor has been publicly advocating for John Edwards for months now, and there are signals that the Culinary Union was far from pleased with the international’s decision to hold off until New Hampshire, delivering the news without the usual fanfare.

That said, it’s unlikely the union wouldn’t decide on an endorsement. After nearly an entire year of carefully cultivating an image of itself as kingmaker of the Nevada caucus, the Culinary’s reputation is on the line.
