For what it's worth: SFGate is reporting a multiple-sourced story that Obama refused to have his picture taken with San Francisco Mayor Newsom back in 2004 after Newsom aggressively advocated for gay marriage.
In all fairness, the piece also says then-presidential candidate John Kerry also avoided San Francisco.
Though same-sex marriage is still a hot-button issue in 2008, it is no longer the shocker that had the country in an uproar four and five years ago. Until you go back and look at the news stories from those days, it is easy to forget how radical and unpopular Newsom's stand was.
And, no, it wasn't just the right-wingers who were upset. It was Democrats, too, particularly those running in the presidential primary. John Kerry, for example, was careful to stage his Bay Area appearances in Oakland, not San Francisco, after the controversy hit.
But Newsom still harbors resentment toward Obama.
But just four years ago, current Democratic presidential candidate Barack Obama is said to have declined to have his picture taken in San Francisco with Newsom, who was then at the center of a national uproar over his decision to allow same-sex marriage in San Francisco.
"I gave a fundraiser, at his (Obama's) request at the Waterfront restaurant," said former San Francisco Mayor Willie Brown. "And he said to me, he would really appreciate it if he didn't get his photo taken with my mayor. He said he would really not like to have his picture taken with Gavin."
Today, of course, Obama's people are backpedaling away from that account like crazy. His deputy campaign director, Steve Hildebrand, who lives with his partner as an openly gay man, calls it "a ridiculous story."
"Barack Obama gets his picture taken with gay people all the time," Hildebrand said. "Including me, his deputy campaign manager."
But insiders at City Hall, both current and former members of Newsom's staff, recall the incident well. And you can bet that Newsom hasn't forgotten it either.
"He was pissed," said one former staffer.
In fact, early last year, Newsom alluded to the incident in an interview at the World Economic Forum in Davos, Switzerland. Speaking to Reuters on Jan. 26, 2007, Newsom was asked about three potential Democratic candidates: Obama, Hillary Clinton and Al Gore.
For what it's worth. The snubs are adding up.
"One of the three Democrats you mentioned as presidential candidates, as God is my witness, will not be photographed with me, will not be in the same room with me," Newsom told Reuters, "even though I've done fundraisers for that particular person - not once, but twice - because of this issue."
Newsom signed onto the Clinton camp many months ago. This looks like a big reason for his decision.
Update: Commenters are speculating Obama snubbed Newsom because he was embroiled in scandal. The affair Newsom had that embroiled him in scandal happened two years after this incident.
