It’s no secret the Hollywood community wants four more years of President Barack Obama. A new report puts some numbers on that fixation.

Through Oct. 21, 198 “celebrity” donors have given $684,006 to the Barack Obama campaign compared with 14 donors who have given $43,250 to Mitt Romney’s camp, according to the Center for Responsive Politics, the leading organization that tracks donations. For those keeping score, that’s a 16-to-1 advantage for the incumbent over the Massachusetts governor.

Among the actors, producers and directors who have given the Obama campaign at least $5,000 are Cameron Crowe, Will Ferrell, Ron Howard, Scarlett Johansson, Julia Louis-Dreyfus, Eddie Murphy, George Clooney, J.J. Abrams, Ellen DeGeneres, Leonardo DiCaprio, Robert Downey Jr., Jamie Foxx, Brian Grazer, Adrian Grenier, Tom Hanks, Mariska Hargitay, Will Smith, Aaron Sorkin, Steven Spielberg, Barbra Streisand, Quentin Tarantino, Marlo Thomas, Sam Waterston and Rita Wilson.

The figures quoted here are just a fraction of the story. Consider the millions poured into pro-Obama Super PACs by Steven Spielberg, Morgan Freeman, Bill Maher and other celebrities. Let’s not forget the clout of celebrity bundlers like Harvey Weinstein.

Plus, Hollywood continually cranks out pro-liberal messages in its content, from impassioned documentaries to blockbusters like “Avatar.”
