Barack Obama is sitting pretty ten days before the Nevada caucuses, having snagged the endorsements of the Nevada chapter of the Service Employees International Union as well as the Culinary workers and their parent union, UNITE HERE. UNITE HERE is the first national union to endorse Obama.

In September, the national SEIU was very close to endorsing Edwards, but backed off and left the decision to state chapters. Since then, 11 state chapters of the SEIU have backed Edwards, and four or five have backed Obama.

We are seeing the consequences of Iowa failing to deliver for John Edwards. The Nevada unions were ready to jump in for him if he had won here. He also would have been helped in Nevada by the California SEIU, which has already endorsed him. But now that the Nevada SEIU is behind Obama, state chapters backing other candidates can’t send their members to campaign in Nevada.

Edwards was never likely to do well in New Hampshire, but he would have had a real shot at Nevada with union backing. Now he is forced to focus on South Carolina, where he is substantially behind Obama and Clinton in the polls.

If Obama does win the nomination and the presidency, I seriously doubt he will do much for labor unions. That would interfere with his posturing as the bipartisan president pushing a unity agenda.

But it isn’t the first time labor unions have picked the candidate they viewed as most likely to win, rather than the candidate most likely to become their champion. That’s the way the world works.

UPDATE: Over at MyDD, Jonathan Singer wonders if these endorsements post a danger to Obama by raising his expectations in Nevada, where he has trailed Clinton in the polls:

SECOND UPDATE: Daily Kos user greenmountainboy was just in Nevada and has this to say:

The union workers and precinct captains are PISSED that their leaders pulled this crap of not supporting Edwards. They continue to run house parties for him and love the man. The power structure (Clinton and Obama) know that if Edwards gets any roots in ANY ONE of these states they are in for a real fight. If that happens watch how quickly Clinton and O’Baby join forces for “change”.
