There's a big difference between the Hollywood liberal crowd, who have always been hardcore Obama fans, and the lobbying wing of the MPAA. They are not the same community.

How are they not the same community? The MPAA is Walt Disney, Paramount, Sony, Fox, Universal, and Warner Bros. The people at these Hollywood fundraisers work for and with Walt Disney, Paramount, Sony, Fox, Universal, and Warner Bros.

When the MPAA threatens to cut off funds, the implication isn't just that whatever amount the MPAA has to throw around will go away, it is that the big dollars from the 6 member studios and the super rich executive and celebrity donors will go away. But you still see that money flowing. Just one example, also from Hollywood Reporter, "Jamie and Michael Lynton - He’s CEO of Sony, and she’s a veteran Democratic activist. The two are raising $500,000-plus for Obama this season. Michael has had almost a dozen meetings at the White House, some regarding anti-piracy."

Because the MPAA and RIAA represent the owners and executives of the movie and record companies. "Hollywood" is also comprised of moneyed actors, musicians and artists that generally tend to lean to the left politically. There is definitely a difference between the two "camps"
