Scoring an invitation to a White House state dinner is the height of social relevancy in Washington, so we thought we'd comb through the 300 plus guest list for Tuesday night's confab honoring India for K Street connections.

We could only find one obvious registered lobbyist on the list -- former Rep. Tom Downey, D-N.Y., and chair of lobbying firm Downey McGrath Group. Downey is also married to Carol Browner, chair of the White House Office of Energy and Climate Change Policy, who was invited to the dinner. She brought her husband as her guest.

Vernon Jordan, senior counsel at top law and lobbying firm Akin, Gump, Strauss, Hauer & Feld, was also on the guest list. Jordan however, isn't a registered lobbyist. His wife Ann was invited to the dinner.

On the list were also a few fundraisers for President Obama's presidential campaign. They included Mark Gorenberg, who helped round up money in Silicon Valley for Obama and Brian Mathis, a New York financier with Provident Group.

Labor unions were also a key support of Obama's campaign. Three guests from that world included Andy Stern, president of the Service Employees International Union, Anna Burger, chair of Change To Win and Richard Trumpka, president of the AFL-CIO.

Of course, Hollywood types were also invited. They included director Steve Spielberg, Michael Lynton, CEO of Sony Pictures, Jeffrey Katzenberg, CEO of DreamWorks Animation, and billionaire David Geffen. (National Journal colleague Jim Barnes notes that Geffen, Katzenberg and Spielberg all held an early and important Hollywood fundraiser for Obama in February 2007 just as the campaign kicked off. It was also there that Geffen said some snarky things to columnist Maureen Dowd about then candidate Hillary Clinton. We noticed that Geffen was not seated at Clinton's table for the state dinner. Hmmm)

Two other well known business types on the guest list: John Doerr, partner at Silicon Valley venture capital firm Kleiner Perkins Caufield & Byers and Jeffrey Immelt, CEO of General Electric. Both have been making big investments in green technology, a key issue of Obama's.
