Tina Daunt posits in her Cause Celebre column in today's Calendar that Hollywood's Hillary contingent is on the verge of buying tickets on the Barack Obama bus.

On desks all over Hollywood, there's a note this morning waiting to be sent:

Memo to Sen. Hillary Rodham Clinton: We think you're aces. Really. And we love your husband. But we're running off with Sen. Barack Obama. Hope you understand. It's all about being part of history. We'll do lunch after the inauguration.

Of course, in certain Westside mansions, loyalty to the Clintons runs deeper than any primary result. But in a town that for many months has been divided by head and heart, a lot of entertainment industry people who chose Clinton because she was the smart choice, the "inevitable" Democratic candidate, are going where their hearts have long wanted to take them -- to a place on the Obama bandwagon (and nobody wants to miss the last seat).

If Clinton loses in New Hampshire tonight, predicted longtime political operative turned Hollywood producer Brian Quintana, Hollywood "will defect to Barack in droves."

"It is not a question of loyalty; Barack is simply too close to making history for Hollywood not to be part of it," Quintana said. "For most of us, Hillary was our first choice, but she has come up short. Barack has become a movement."

David Geffen will brief the newbies on their talking points tomorrow at noon (and again at 2 pm) at the Chateau Marmont. Striking writers park for free.

Oops: Mark Lacter already got there.
