SEIU 4 Obama?

CNN is reporting that the Service Employees International Union (SEIU) is "poised to endorse Sen. Barack Obama for President." According to CNN:

Three sources familiar with the deliberations said union leaders met via conference call Thursday to deliberate on the endorsement issue. These sources, speaking to CNN on condition of anonymity, said Obama was the overwhelming choice of the union's state and national leadership.

While I'm hesitant to put major weight behind anything anymore, SEIU has to be seen as a positive for Obama, particularly within the upcoming primary states. Another positive for Obama is that the likelihood of John Edwards endorsing Sen. Clinton, given all he did to court SEIU local and national leadership as a candidate, would seem more farfetched if the SEIU endorsement is real. Though I guess with all the twists and turns thus far, anything is still possible...

Update: SEIU has endorsed Obama. From the AP:

Sen. Barack Obama won the support Friday of the 1.9-million member Service Employees International Union, his second endorsement in as many days from large labor organizations and a fresh sign of momentum in the Democratic presidential race with Sen. Hillary Rodham Clinton.

"There has never been a fight in Illinois or a fight in the nation where our members have not asked Barack Obama for assistance and he has not done everything he could to help us," Andy Stern, the union's president, told reporters in announcing the decision.

Stern said that in the months since union leaders met with several Democratic candidates last fall, "the excitement has been building and building for Obama."
