I wrote earlier that UNITE-HERE, the big, merged hotel and textile workers' union was "expected" to back Edwards, which would be huge in Las Vegas.

And, as I should have known, it's not quite that simple.

While the international may be expected by New York and D.C. insider types to back Edwards — he and its president, Bruce Raynor, are close, and Raynor's former chief of staff Chris Chafe actually now works for Edwards — the implications for Nevada are nowhere near that clear.

Pilar Weiss, the political director of Culinary Union Local 226 — the key Las Vegas hotel workers' affiliate of UNITE-HERE — says the New York-based leadership won't make the call for the Nevada local.

"There are people in our union who have a relationship with Edwards, but we've made it very clear to the candidates that they'll have to win our endorsement in Nevada," she said. "There's no New York-based automatic stamp."

So stay tuned: "We'll make an endorsement late, in December, when our members are ready to make a decision about who best fits their hopes."
