If you stopped by Culver Studios on Tuesday, you might have heard this: “Hi … this is Michael Lynton, and I’m a volunteer with Organizing for America, President Obama’s grassroots campaign. How are you?”Lynton, along with wife Jamie, stopped by the Culver City phone bank on election day, where organizers were expecting 600-700 volunteers to pass through the doors of soundstage 3. The Sony topper missed co-chairman Amy Pascal, who had already volunteered before 9 a.m. Campaign bundler Jamie Lynton sported a custom-made silver necklace with the Obama rising-sun logo. Top California Obama campaign staffer Mary Jane Stevenson gave Lynton the necklace after the 2008 election. Jamie Lynton began volunteering for Obama since “the day he announced” in 2007. “I will be here until we get to declare victory. I sent out an email to about 550 people and told them to get out here,” Jamie Lynton said, moments before her proud husband walked up to say that their eldest daughter had cut school to volunteer. Bizzers including Cameron Crowe and Julia Louis-Dreyfus also stopped by to cold-call residents in states including Colorado, Ohio and Wisconsin. (Louis-Dreyfus even made a video of herself making calls, which can be seen on her website.) Volunteers estimated that as many as 1 million campaign calls originated from California on Monday, making it one of the most active grassroots non-battleground states. Several volunteers nearly wandered into the soundstage next door, where dozens of women were heading into a live taping of “The Ricki Lake Show.” Asked what the atmosphere was like at the nearby Sony lot, Michael Lynton said there was support for both sides, although he pointed out that most of the support for Republican nominee Mitt Romney came less from inside Sony and more from producers and others around the lot.
